A set of steady inviscid equations governing the flow along a given S₂ relative stream surface in a mixed-flow turbine runner having a finite number of thick blades was obtained. By applying the streamline-curvature method, this set of equations can be solved. A computer program is developed in order to calculate the flow field on the S₂ surface. The comparison with the results of the potential flow theory shows a marked effect of the blade loading.
