Abstract

Centrifugal compressors are widely used for several
purposes in many industries. Aero defense industry uses these compressors in
the engines of several structures. In the present study, the centrifugal
compressor of a mini jet engine is designed with the utilization of
Computational Fluid Dynamics (CFD) tools with the methodology developed. The
designed compressor is manufactured and its tests were conducted using an
engine that is being utilized commercially. The performance parameters of the
designed compressor and the results obtained from the engine were compared and
presented. The specifications of the designed compressor was determined in the
light of the requirements of the test engine. It was observed that the obtained
mass flow rate (0.678 kg/s), pressure ratio (4.6135) and the efficiency
(92.38%) values are within the limits of the design specifications and the
although there is a slight difference between the results of the CFD analyses
and the experiments, the trends of the curves are consistent with each other.
