Abstract

A practical combined computation method of the circumferentially averaged mean through-flow is presented for 3D inverse computations of hydraulic turbomachinery blades to consider the influence of interrelated hydraulic components. A comprehensive computation domain including the runner blades and related components is adopted and the mean flow is calculated altogether by solving a set of rotational flow governing equations simultaneously. The method has been applied to the case of Kaplan turbine. Computational results were compared to experimental data and their agreement was confirmed. Numerical investigation indicates that the mean flow is dependent on the configuration of guide vanes and the effect of runner blades reaches to the far upstream. The importance of properly taking account of the effect of blade geometry and the influence of interrelated hydraulic components is demonstrated.
