314Static pressure distribution and flow

Static pressure measurement on the blade surface is performed using the pressure blade. For the two dimensional flow, the middle row of pressure taps is used for obtaining the mid-span static pressure on the blade surface. During the measurement, the mainstream velocity is about 20m/s with a exit Reynolds number of 6.0 x 105. The measured distribution of static pressure coefficients at mid-span of the central blade, as well as the static pressure coefficients predicted from inviscid flow solution, are plotted in fig. 3.4(a). The measured coefficients on pressure side agree well with the predicted curve from the inviscid prediction,
