Endwall Blockage in Axial Compressors [PDF]
Volume 1: Turbomachinery, 1998 This paper presents a new methodology for quantifying compressor endwall blockage and an approach, using this quantification, for defining the links between design parameters, flow conditions, and the growth of blockage due to tip clearance flow. Numerical simulations, measurements in a low speed compressor, and measurements in a wind tunnel designed ...

The New Performance Calculation Method of Fouled Axial Flow Compressor
The Scientific World Journal, 2014 Fouling is the most important performance degradation factor, so it is necessary to accurately predict the effect of fouling on engine performance. In the previous research, it is very difficult to accurately model the fouled axial flow compressor.

A turbojet simulator for Mach numbers up to 2.0 [PDF]
A turbojet simulator was designed and fabricated for use in wind tunnel models. The simulator contains a six-stage, axial-flow compressor powered by a three-stage, axial-flow turbine. High pressure heated air was used to drive the turbine.
