ANALYSIS OF THE FLOW IN RADIAL COMPRESSOR OF THE SMALL JET ENGINE MPM-20

Abstract

This thesis focuses on CFD analysis of airflow by centrifugal compressor of a small jet engine MPM-20, located in the laboratory of small jet engines in the faculty of aeronautics. In the introduction is developed thermodynamic calculation of the centrifugal compressor having aims to create conditions for comparison with CFD analysis. Another part of the work is divided chronologically as they respect the gradual development of the project and are the following parts: creating appropriate geometric model, the subsequent creation of computer mesh for geometric models and the creation of a computational model, further analysis using CFD methods, evaluation of the results and conclusions of the examination and comparison of CFD analysis with numerical calculation.
