Study of the critical flow rate across cascades of thin, slightly bent profiles by the method of ?large particles?

Abstract

A study was made, numerically by the method of “large particles” and experimentally, of the critical flow rate across plane cascades of wing profiles at subsonic velocities and variable angles at the inlet, and large supersonic velocities at the outlet. The variation of the critical flow rate as a function of the inlet angle is given for various types of cascades.
