Aerodynamic analysis of anti-surge modifications on turboprop engine
Novák, Ondřej ; Zima, Martin (oponent) ; Popela, Robert (vedoucí práce)
This thesis is focused on aerodynamic analysis of principles of increasing surge margin. The first chapter introduces aerospace compressors and sets up baseline knowledge of compressor characteristics and anti-surge devices. The second chapter provides detailed description of CFD model, settings, mesh dependence study and correlation with experimental data. The third chapter contains data from baseline configuration and identifies problematic areas of 1st stage compressor. The fourth chapter contains information obtained from CFD of each anti-surge device and subsequent process of optimalization. The thesis is concluded with comparission of the best version of each device using two objective criteria.
