The article proposes a method for the interrelated determination of the speed coefficients and optimal geometry of a radial-axial centripetal turbine flow range. The method is based on a model of gas flow at an average diameter in a one-dimensional quasi-stationary approximation, supplemented with ratios to determine the optimal operating parameters of the turbine.
