Task / Calculation
The filling of a turning water wheel is to be calculated by means of CFD simulation. An optimum filling of the blades is to be achieved via intake conditions and the rotation speed of the water wheel. The calculaltion was realized with dynamic grids in consideration of two phases (water, air) and free surfaces.
- Problems at the water feed could be identified
- Flow as well as blade shade could be optimised in a way leading to very low water feed losses at design point with maximum blade filling
