2. Description of Related Art
As fluid is funneled towards impeller blades, present day turbine applications employ a variety of mechanisms to increase their effectiveness including, modifying static elements, rotating elements, or major upstream or downstream civil works alterations, all of which require major costs and extended shutdowns periods. Each of these mechanisms act to supply additional fluid towards impellers. Unfortunately, numerous mechanisms require adding additional components to turbine, modifying the shapes of the turbine along with the shape of the impeller. Thus, there exists a need for an application which can increase the available power from a rotating assembly, which allows for fluid flow to be added to fluid flow and additional head on to the current fluid mechanism.
The novel features believed to be characteristic of the invention are set forth in the appended claims. However, the invention itself, as well as a preferred mode of use and further objectives and advantages thereof, will best be understood by reference to the following detailed description when read in conjunction with the accompanying drawings, wherein:
Referring now to the Figures,
In an exemplary embodiment of the present application, turbine system 10 can include one or more uprights 60 positioned in an orientation substantially parallel in the same plane to one or more impellers 70 to effectuate a flow regime.
In an alternative embodiment of the present application, turbine system 10 may include one or more uprights 60 which are of varying lengths. For example, uprights 60 may individually extend to a non-uniform orientation relative to one another. One upright 60 may extend to a specified length, while another upright 60 may extend to another length, while still another upright 60 extends to yet another length.
Portions of uprights 60 may form various shapes, and may act to influence fluid disposed towards impellers 70. For example, as is illustrated in
By positioning uprights 60 relative to impellers 70 various goals can be achieved. For example, in certain embodiments, uprights 60 may be positioned behind impellers 70 so that additional fluid pressure can build and in turn to supply further as fluid is communicated through turbine system 10. Similarly, uprights 60 can be disposed in front of impellers 70 in order to allow for added rotation of fluid, orthogonally, or nearly so, as fluid contacts turbine blade to generate the transfer of energy through turbine system 10.
Further, uprights 60 may be of various shapes and sizes. In certain embodiments, uprights 60 may be positioned in a fashion such that they are substantially flexible to allow for fluid to be transmitted in an orientation towards impellers 70. In another embodiment, uprights 60 may be substantially rigid such that fluid is deflected towards the orientation of fluids. In certain embodiments, uprights 60 may positioned in a direction in an angle positioned less than less than ninety degrees. In other embodiments uprights 60 may be of varying angles and of varying orientations.
Uprights 60 may initially extend at a ninety degree orientation relative to cylindrical housing 20 and as they extend towards center of turbine system 10, begin to taper to lesser degrees. Such a scenario is optimal when additional fluid is being naturally transmitted towards turbine system 10 in a non uniform fashion. For example, if fluid was naturally travelling in a non-laminar flow and a higher degree of fluid was being transmitted towards center of turbine system 10 and an upright 60 extending at initially ninety degrees (as is shown) was incapable taking optimal advantage of received fluid energy, another portion of upright 60 could beding to curve between twenty and sixty degrees in order to be placed in contact with an optimal amount of fluid energy.
In certain embodiments, one or more uprights 60 are circumferentially disposed about an inner diameter of a turbine input and extend about the diameter of a turbine. The turbine may be of the type with a static shrouding or may include a rotating apparatus.
In yet other embodiments, uprights 60 may extend from impellers 70 in a pattern that allows for a swirl to be created as fluid is transmitted through turbine system 10. Uprights 60 may extend from impellers 70 in an outwardly extending fashion. For example, in certain embodiments impellers 70 may increase in length as they extend outward from uprights 60. If only three impellers are employed, as each impeller 70 extends towards rotating ring 50, additional space between impellers becomes available. Thus, numerous uprights 60 may extend from each impeller 70 and may increase in length as additional space becomes available, In certain embodiments, although only a limited numbers of impellers may be employed, each upright 60 may extend from each impeller 70 to the same length.
In a preferred embodiment, uprights 60 can extend about an inner diameter of a turbine and are oriented towards a direction of impeller 70 while being preferably positioned according to the direction of the flow. In certain embodiments, uprights 60 can tangentially extend about a turbine input at an angle which is substantially perpendicular to a turbine input. In other embodiments, some of uprights 60 may be oriented at an angle ranging between 0° and 180° and may extend towards the directional fluid flow or against the direction of a fluid flow and may be of variable flexibilities or multi-dimensional curvatures. In alternative embodiments, each of uprights 60 may extend at an orientation and height which does not necessarily extend to a same height and orientation as another of uprights 60.
In other embodiments, uprights 60 may extend to form various shapes and may extend to form a ninety degree angle such that an upright begins by extending substantially perpendicular to a turbine input and curves such that an end of upright 60 extends substantially parallel to the direction of fluid flow. In certain embodiments, uprights 60 may be fixably coupled to a turbine input, while in other embodiments uprights 60 may be removably coupled to a turbine input.
Each of uprights 60 may of a variable thickness, height, and width and extend to different lengths of said turbine or rotating ring for further increasing fluid flow into turbine impellers. In a preferred embodiment of the present application, uprights 60 are made of a semi-rigid material and allow for slight flexing. In other embodiments of the present application, uprights 60 can be comprised of a non-rigid material and in yet other embodiments of the present application, uprights 60 are comprised of a rigid material. In certain embodiments, several of uprights 60 may be made of a rigid material while other uprights 60 are made of a non-rigid material and yet other uprights 60 are made of a semi-rigid material.
In yet other embodiments, uprights 60 may be disposed above or below the surface of said rotating ring or said turbine shroud and makes into a length that is separate from said turbine impellers 70 between ranges of 0.0001 inches up to just less than the length of the turbine impellers 70.
In operation, as fluid begins to flow through a turbine input, uprights 60 cause a more efficient fluid flow through turbine impellers by channeling water further towards the direction of impellers 70 such that a greater amount of flow is exerted upon turbine impellers 70. Use of uprights decreases lost power generation due to water which escapes between the gaps of a turbine input and its corresponding separation from the impeller.
