Abstract

Abstract

A calculation method is proposed to determine the blade section drag instead of sophisticated experimental measurement of it. Since it is possible to obtain the detailed distributions of velocity and pressure on the boundary line from the wake measurements behind a compressor rotor. By using these distributions, the blade section drag is determined by means of the momentum equation of integralrepresentation and appropriate mathematical manipulation.
