Choice of the parameters for calculation of the radially-axial turbines working in conditions of the non-stationary stream

The paper considers the designing problems of geometrical parameters choice of a flowing part of a radial-axial turbine . The J A. A. Sirotkins mathematical model on a direct problem of axe symmetric vertical current is offered to apply for the analysis of the chosen geometrical parameters. The calculations results are presented on the example of the radial-axial turbine of the ТКР-14В-30 turbocharger.
