Creation of Parametrized Model of Transonic Axial Compressor Flow Path for CFD-Researches

Computer programs for primary design based on mathematical pressure losses model and A. Komarov's model of flow deviation angle are used at the first stage of axial compressors flow path creating. To conduct a gas dynamic study 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 with the next goal: the obtained by the primary design program flow path geometry is transferred to the ANSYS CFX software package. When copying data, the blades, meridian contour and computational grids are automatically constructed. The resulting model is ready for further gas dynamic calculations.
