Simultaneous measurment of fluctuating velocity and pressure using time-resolved PIV and miniature static-pressure probes

Simultaneous measurement of the fluctuating velocity and pressure is performed combining a miniature staticpressure probe and a time-resolved PIV aiming at further improvement in evaluation of the velocity-pressure correlation. Two static-pressure probes were placed in the measurement domain of the time-resolved PIV and the instantaneous velocity field and the fluctuating velocity are measured simultaneously. The instantaneous pressure filed is estimated from the measured velocity field by numerically solving a discrete Poisson equation for pressure. The values of the estimated pressure are corrected based on the pressure values which are directly measured by the static-pressure probe.
