Abstract
The problems of creation and calculation of virtual numerical models in the stage of an ultra-low power axial turbine are considered. A method for constructing the calculation area of the flow in an axial turbine and a finite element grid superimposed on this area is given. The characteristics of the power efficiency and specific power of the turbine are obtained depending on the pressure ratio and the loading parameter. The results of the numerical experiment are verified with the data of the full scale experiment.
