Three dimensional flow simulation of load rejection of a ...
2012-4-28u2002·u2002Three dimensional (3D) unsteady, incompressible flows in a pump-turbine during a transient process of load rejection were studied using the computational fluid dynamics method. The dynamic mesh (DM) method and remeshing method combined with non-conformal grid boundaries were applied to simulate the rotation of guide vanes. The fluid coupling and DM method were used to calculate the …
