Experimental investigation of shock-induced separation and flow control in a transonic compressor cascade

EXPERIMENTAL INVESTIGATION OF EFFECTS OF WALL POROSITY AND SUCTION ON THE FLOW QUALITY IN A TRANSONIC WIND TUNNEL

A trisonic wind tunnel has been modified to improve its flow quality when operating at transonic speeds through perforated walls and side suctions. The usefulness of such a perforated wall, already known, is reduction of the blockage effect as well as the shock elimination. Two types of perforated walls have been used in this investigation. The first wall had a porosity of about 22% and the hol...

Laser Anemometer Measurements in a Transonic Axial Flow Compressor Rotor

experimental and numerical flow investigation through a radial flow compressor volute

an optimal design and fabrication of compressors requires flow investigation through the compressor components. flow field inside the volute is fully three dimensional and turbulent. better understanding of flow mechanism leads to improve the volute design procedure. in this research the experimental and numerical flow investigation through a radial flow compressor volute are performed to recog...

Scroll Compressor Flow Modeling: Experimental and Computational Investigation

Unsteady Transonic Flows in an Axial Flow Compressor*

Introduction. This paper deals with some transonic flow problems for the supersonic axial flow compressor: these arise in connection with flutter analysis for fan blading. Very detailed solutions for unsteady plane transonic flows through a cascade of flat plates have been given by Goldstein Braun and Adamczyk (1977) and Nagashima and Whitehead (1977), see also Goldstein (1975), Kurosaka (1974)...
