DEVELOPMENT OF A PARAMETRIZED MODEL AND CALCULATION OF A POWER UNIT AXIAL COMPRESSOR

Computer programs for primary design based on mathematical models of pressure losses and A. Komarov’s model of flow deviation angle are used at the first stage of constructing axial compressors flow path. To conduct a gas-dynamics research using CFD methods, it is necessary to create a computational model of the flow path obtained as a result of the design. The paper describes the main points of creating a parameterized design model of a four-stage axial compressor. The parameterization is carried out in a way to ensure that the geometry obtained by the primary flow path design program is transferred to the ANSYS CFX software package. When copying the data, the blades, meridional contour and computational grids are constructed automatically. The resulting model is ready for further gas-dynamics calculations. The use of the parameterized model enables optimization with several adjustable parameters and various criteria of efficiency.
