Flow in a Pelton Turbine Bucket: Numerical and Experimental Investigations

The flow model used for the numerical simulations is based on the generalized homogeneous multiphase flow model developed by Ishii 15, with the additional sources of momentum for the effects of the Coriolis and centrifugal accelerations in a steady rotating frame of reference. The governing equations are described below

A Three Dimensional Spiral Casing Navier-Stokes Flow Simulation

Navier-Stokes flow simulations are now commonly used in the process of hydraulic turbomachinery design. Comparison with experiments and careful understanding of the behavior of such tools is however very important to the correct interpretation of the results. Following this trend, Navier-Stokes flow simulations, using three solvers, applied to a pump turbine spiral casing in turbine mode, are presented and discussed in this paper.
