Abstract

A concept of the new measurement of velocity in subsonic air-flow is shown. This method uses Schlieren method and PIV method using pressure wave image. In this method, the ordinary tracer particle is not necessary because the pressure wave, which propagates in subsonic flow is used as tracer image. This study aims to construct the principle and to mention the merits and demerits of this method. The experimental study in one dimension was done and it was appeared that the result agrees with the theoretical value and the difference is less than 10 percent in this method. We are going to try and evaluate this method in two dimensions.
