Abstract
The evaluation method of pressure distribution using the velocity field measured by micro PIV is studied in a straight micro-channel flow with square cross section. In this method, the three-dimensional velocity field is assumed parabolic except for the experimental cross-sectional velocity distribution measured by micro PIV The comparison between the evaluated pressure drop and the numerical result by Navier-Stokes equation indicates good agreement with each other, which suggests the validity of this method for evaluate the pressure drop in the micro channel.
