The paper describes an algorithm for the designing of axial and radial-axial type turbines. The algorithm is based on using mathematical models of various levels of difficulty – from 1D to 3D. Geometry description of flow parts is performed using analytical methods of profiling using a limited number of parameter values. 3D turbulent flow model is realized in the program complex IPMFlow, developed based on the earlier codes FlowER and FlowER-U. The examples of developed or modernized turbines for different purposes power machinesare presented. They are an expansion turbine, ORC turbine, cogeneration medium-pressure turbine.
