Research Abstract |
A novel method for measuring the pressure and velocity fields of unsteady flow around bodies was constructed. The measurement technique using fast responding pressure-sensitive paint (PSP) was improved to detect the pressure fluctuation whose frequency and amplitude are 5 kHz and less than 100 Pa. An analytic solution of the frequency response of the PSP signal was derived in which the effect of luminescence lifetime was considered. A coupled system using this PSP and the time-resolved particle-image velocimetry (PIV) was constructed. Wind-tunnel test of this system indicated that the sheading droplets for PIV hardly disturbed the signal from the PSP. The vorticity obtained by PIV correlated well with the pressure fluctuation measured by PSP.
