description: In this paper, we analyzed the influence of geometric parameters on losses in inter-turbine diffusers.Â  A three-dimensional model of the flow part of the block "CT stage - transitional diffuser - ST stage" in the SolidWorks environment was built.Â  Using the ANSYS ICEM CFD program, a grid partitioning of the design model of the transitional diffuser was performed.Â  In the ANSYS Turbogrid program, a grid partitioning of the calculation model of the CT and CT blades was performed - separately for the guide vane and the impeller.Â  In the CFX-Pre program, a calculation model has been developed, which is a sector of the flow path.Â  A gas dynamic calculation was carried out in the ANSYS CFX program.Â  A study of the flow structure in the transition channel in the block "CT stage - transition diffuser - ST stage" was carried out.Â  Calculations of the flow path with modified geometry were performed.Â  Based on the results of the study, a conclusion was made about the most optimal geometry of the transitional diffuser.
