Claims
- 1. A method for visualizing aerodynamic flow effects on a test surface, comprising the steps of:
- coloring discrete quantities of a sublimating chemical different colors;
- applying a first uniform colored layer of the sublimating chemical to the test surface;
- applying a second, different colored uniform layer of the sublimating chemical to the first applied layer to form a composite of layers of different colored sublimated chemicals; and
- subjecting the test surface and composite to an airflow, whereby the layers of the composite are removed by the airflow to create a portrait of the aerodynamic flow effects on the underlying test surface.
- 2. The visualization method according to claim 1, futher comprising applying additional different colored uniform layers of sublimating chemical to said second layer of colored sublimated chemical to form a composite of more than two different colored layers of sublimated material.
- 3. The visualization method according to claim 2, wherein said coloring step comprises mixing discrete quantities of the sublimating chemical with oil-based paints of different colors.
- 4. The visualization method according to claim 2, wherein each layer is of the same thickness.
- 5. The visualization method according to claim 1, wherein the sublimating chemical is naphthalene.
- 6. The visualized methods according to claim 5, wherein said coloring step comprises mixing discrete quantities of the sublimating chemical with oil-based paints of different colors.
- 7. The visualization method according to claim 1, wherein said coloring step comprises mixing discrete quantities of the sublimating chemical with oil-based paints of different colors.
- 8. The visualization method according to claim 1, wherein each layer is of the same thickness.
