Calculation of flow in the gas turbine and the outlet tract using CFD methods

This paper deals with the calculation of 3D flow in a gas turbine and a nozzle with variable geometry of small jet engine ISTC-21V placed in a laboratory LIRSLM at Faculty of Aeronautics. It was used methods of meshing around the geometry of the CAD model and the CFD calculations for viscous flow. The resulting data was then compared to the measured in the laboratory and calculated from the analytical model of the engine. The evaluation has proved the credibility of the calculation to be used as additional knowledge of engine parameters.
