This paper investigates the effect of rotor-stator spacing and operating conditions on compressor performance interaction mechanism. We focus between rotor wake stator’s flow field through several unsteady numerical simulations aiming at a transonic stage in equal radius path with two-axial three conditions. The simulation results indicate that time-averaged efficiency almost declined by 0.6 po...

in this paper it is attempted to investigate the behavior of an inviscid flow in the meridional plane of an axial flow compressor. for this purpose the 3-d unsteady euler equations in cylindrical coordinate are averaged in tangential direction. therefore, the equations are reduced to a 2-d system. by averaging the tangential component of momentum equation, a blade force will result. axial and r...

Abstract High-speed compressor testing is costly due to mechanical complexity and hazardous the high energy involved. In past this has limited speed amount of testing. paper a new rig architecture presented that aims test scaled transonic stage rapidly. It builds upon low-speed rapid developments made at Whittle Laboratory potential accelerate technology development. The power input requirement...

A small transonic wind tunnel was designed, constructed and calibrated in order to provide a tool for the study and demonstration of transonic flow phenomena. The wind tunnel makes use of flow properties following the propagation of a shock wave along a tube in order to create the transonic flow. This is in contrast to conventional transonic facilities which are supplied from a reservoir or com...
