| Outline of Final Research Achievements |
We developed the measurement system for detecting unsteady surface pressure field by fast-responding pressure-sensitive paints (PSP). Ultimate goal of our study is to analyze the surface pressure field on rotating machinery such as fan and wind turbine. First, we precisely determined the pressure, temperature and humidity sensitivities by a new apparatus in which these quantities are varied independently. We presented the pressure signal measured by PSP is correlated well with vorticity field measured by particle image velocimetry. Then we developed a sophisticated image processing technique by which we dramatically reduced error on unsteady pressure measurement within 10 Pa. Finally, we successfully measured pressure field on rotating fan within the range of 100 Pa. We found that the measured pressure distribution agrees well with the distribution calculated using large-eddy simulation.
