Влияние гидродинамических характеристик элементов проточной части на энергетические показатели радиально-осевой гидротурбины

Abstract

In the given work hydrodynamic characteristics of elements of a flow space of the Francis turbine are defined. Influence of hydrodynamic characteristics on formation of power characteristics of the Francis turbine is established. On the basis of the skilled data the structure and parameters of dependence of factor of losses of the runner from geometrical and regime parameters is defined.
