Present disclosure generally relates to the field of fluid mechanics. Particularly, but not exclusively, the disclosure relates to fluid dispensing devices. Further, embodiments of the present disclosure relate to an injector assembly, for use in applications such as, but not limited to, fuel injection engines.
In fluid mechanics, injectors and atomizers are used for changing state of flow of fluid. Both injectors and atomizers may be used as individual components for performing discrete functions such as, atomizers being used to atomize a fluid, while the injectors being used for injecting the fluid, or the fluid that has been atomized. However, these injectors and atomizers may also be custom fitted or retrofitted to form an integral component, where the injector and atomizer may be programmed to synchronously function, as twin-fluid atomizing nozzles. Such injectors and atomizers may be equipped based on applications including, but not limited to, fuel injection units, food processing units, spray coating units, and the like.
One such application where the twin-fluid atomizing nozzles, or in other words, the injector may be integrated with the atomizer, may be in the fuel injection units of a scramjet engine. The scramjet engines are used in the aerospace industry for propulsion of heavy payload carriers including, but not limiting to, a cargo aircraft, a jet and the like. The scramjet engines, in general, operate on varying fluid pressures, for combustion of fuel mixture to generate optimal thrust. The twin fluid atomizing nozzles or injectors may be employed in the fuel injection units of such scram jet engines, to assist in supplying adequate quantity of fuel mixture by breaking down the fuel mixture into smaller particulates. The smaller particulates may then be subjected for combustion, to generate the thrust, for propulsion.
However, conventionally available twin fluid atomizing nozzles fail to match the operating conditions of the scramjet engines due to various reasons. Some of the problems associated with the conventional twin fluid atomizing nozzles include fuel pressure drop, lower fuel particulate size, liquid flow rate, high flow velocity required for efficient mixing, penetration ability of the fuel particulates and the like. Further, the twin fluid atomizing nozzles may be manufactured specific to their application in relevant fields or industries. Also, the particulate size achieved and injected by the twin fluid atomizing nozzles may not be conducive for scramjet operation, as flow rates, flow capacities and medium particulate size of the particulates are lower than the requirement. Due to the poor performance characteristics of the medium particulate size, that are dispensed by the conventional twin fluid atomizing nozzles, incomplete combustion of the fuel may arise in the scramjet engine, thereby, thrust generated is well short of the required thrust, for propulsion. Thus, resulting in reduction in efficiency of the scramjet engine.
The present disclosure is directed to overcome one or more limitations stated above.
The information disclosed in this background of the disclosure section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgment or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
One or more shortcoming of the prior arts and conventional systems are overcome by providing an injector for use in applications such as, but not limited to, scramjet engines, food processing, spray coating, painting, and the like.

In the following detailed description of the embodiments of the disclosure, reference is made to the accompanying figures that form a part hereof, and in which are shown by way of illustration specific embodiments in which the disclosure may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the disclosure, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present disclosure. The following description is, therefore, not to be taken in a limiting sense.
The second lance (2) is adapted to house a tube member (4). The tube member (4) may be configured to receive the first fluid at a first end (5a), while a second end (5b) of the tube member (4) may be sealed. Here, it may be noted that the first end (5a) of the tube member (4) may be positioned outside the second lance (2) to receive the first fluid, whereas the second end (5b) of the tube member (4) may be introduced within the second lance (2). The tube member (4) is coupled to the second lance (2) at a region proximal to the first end (5a) by a securing means (8). In an embodiment, the securing means (8) may be at least one of a cork plug, a rubber plug, a clamp and the like. Due to the configuration of the securing means (8), the tube member (4) may be suspended within the second lance (2), which in-turn results in circumscription of the tube member (4) by the second fluid flowing through the second lance (2).
Further, the tube member (4) may include at least one recess (6), between the first end (5a) and the second end (5b) of the tube member (4). The at least one recess (6) may be adapted to fluidly communicate the first fluid in the tube member (4) to mix with the second fluid flowing through the second lance (2). This mixing of the first fluid, from the at least one recess (6), with the second fluid, in the second lance (2), results in formation of an effervescent fluid. The effervescent fluid may then be dispensed via at least one of the first exit port (7a) of the first lance (1) and the second exit port (7b) of the second lance (2).
In an embodiment, the at least one first inlet port (3a) is located on the first lance (1), with an axial axis of each of the at least one first inlet port (3a) overlying on a transverse plane (A-A) of the first lance (1), as best seen in
In an embodiment, the at least one second inlet port (3b) may be provisioned in the second lance (2) such that, the at least one second inlet port (3b) may outwardly and perpendicularly extends about the axial axis (B-B) of the second lance (2). Here, one skilled in the art should not construed that the orientation and/or outward extension of the at least one first lance (1) and the at least one second lance (2) to be a limitation of the injector (100). It may be noted that the orientation and/or outward extension may be modified in accordance with various constructional parameters of the injector (50). In an embodiment, the constructional parameters of the injector (50) may be including, but not limited to, number of the inlet ports, required angular induction of the first fluid and the second fluid, volume of the first fluid and the second fluid to be inducted, viscosity of the first fluid and the second fluid, and the like. Also, in an embodiment, the second lance (2) may be longitudinally covered by the first lance (1), due to which, the at least one second inlet port (3b) may extend from the periphery of the second lance and through the first lance, to receive the second fluid.
In an embodiment, the injector (100) during operation may allow the first fluid to flow through the first lance (1) and the tube member (4), while the second fluid may be allowed to flow through the second lance (2). Since the second end (5b) of the tube member (4) is sealed, the first fluid may be allowed to fluidly communicate into the second lance (2). This communication of the first fluid with the second lance (2) may result in mixing therebetween, in the second lance (2). The mixing of the first fluid and the second fluid renders formation of the effervescent fluid, which then results in atomization of the effervescent fluid when dispensed from the injector (100). In addition, the first fluid passing through the first lance (1) assists in propelling the atomized effervescent fluid from the injector (100), to dispense and disperse the effervescent fluid to a wider area. Furthermore, the effervescent fluid may be dispersed from the injector (100) through at least one of the first exit port (7a) of the first lance (1) and the second exit port (7b) of the second lance (2).
In an exemplary embodiment, the first lance (1) includes a first port (3a′) and a second port (3a″) as shown in
Furthermore, in an exemplary embodiment, the first port (3a′) and the second port (3a″) may also be eccentrically positioned about the axial axis (B-B) [as referred from
In an embodiment, due to linear propulsion and/or oblique propulsion, the effervescent fluid, which may be dispensed and dispersed from the injector (100), may be atomized into particulates thereby, resulting in higher penetration length of discharge from the injector (100). It may be noted that, in the linear/oblique propulsion of the effervescent fluid, the particulates may include characteristics such as, but not limited to, fine particle size, higher kinetic energy, and the like.
Referring now to
Further, an exemplary experiment has been conducted for analyzing performance of the injector (100), with water as the second fluid, while air is used as the first fluid. In the exemplary experimental set-up, the tube member (4) is provisioned with twelve recesses. Upon operating the injector (100) for atomizing the effervescent water, an air pressure in the tube member (4) is maintained in the range of about 2 bar to about 2.6 bar. Also, the first lance (1) was maintained unoperated, as no pressurized air was supplied therethrough. It was noted that particulates [i.e. water droplets] were dispensed due to the effervescent water from the injector (100). This effervescent water resulted in formation of the particulates of the water droplets with a mean diameter in the range of about 47 μm to about 48 μm.
Referring now to
Further, an experiment has been conducted for analyzing performance of the injector (100), with water as the second fluid in the second lance (2), while air is used as the first fluid in each of the first lance (1) and the tube member (4). During the exemplary experiment, upon supplying air in the first lance (1), air is pressurized to be discharged from the first lance (1) at a flow rate of about 200 liters/minute to about 400 liters/minute. Fine particulates are configured to be dispensed therethrough. The fine particulates formed may have a mean diameter in the range of about 15 μm to about 18 μm.
Turning to
In an embodiment, the first lance (1) may be supplied with the first fluid, the second lance (2) may be supplied with the second fluid, and the tube member (4) may be supplied with a third fluid. Here, it may be noted that the first fluid, the second fluid, and the third fluid may be elected in such a way that the second fluid and the third fluid form the combustible mixture, while the first fluid may act as the oxidizing agent. However, one skilled in the art should not construe the sequence of supplying fluid to the first lance (1), the second lance (2), and the tube member (3) to be a limitation, as the sequence may be varied per application of the injector (50).
It is to be noted that, the application of the injector (50) may not be limited to the scramjet engine (100), as one skilled in the art would readily recognize that the injector (50) may be employed for applications including, but not limited to, spray coating, food processing industries, cooling, quenching, drying, and the like.
It should be construed that the various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
Equivalents
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation, no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general, such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.
While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
