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.

建立了一种测量物体周围非定常流动压力场和速度场的新方法。改进了快速响应压敏涂料(PSP)的测量技术，以检测频率和幅度均为5 kHz、小于100pa的压力波动。考虑了发光寿命的影响，得到了PSP信号频率响应的解析解。将该PSP与时间分辨粒子图像测速仪(PIV)相结合，构建了一个耦合系统。风洞试验表明，PIV引信液滴对PSP信号的干扰很小。PIV测量的涡量与PSP测量的压力脉动有很好的相关性。
