| Outline of Final Research Achievements |
This study aims at developing a novel method for wind tunnel experiment by developing a new pressure measurement method. The novelty lies in the use of the photoresponsivity of nanoparticles as a means for the measurement of pressure on object surfaces. To achieve this goal, firstly, optimal geometrical and mechanical scales of the experiment were theoretically investigated, taking into account the photoresponsivity of nanoparticles and the relevant similarity laws of fluid dynamics. Then, on the basis of the investigation, a prototype of the experiment device was actually built. Secondly, ways to control the flow of fluid media were developed by using the built experiment device. In parallel to the two abovementioned tasks, the optimization of nanoparticles was theoretically and experimentally conducted. With these tasks, the research group has succeeded in developing elements of techniques required for the realization of the novel wind tunnel experiment method.
