CFD simulation is aimed on the two-stage pump operation modeling in the pump and turbine regime. The flow analysis will be focused on the proper angle of wicket gates attack and on the separation localization. This investigation should bring the geometry modifications that will increase the hydraulic efficiency. The computational model was created in preprocessor GAMBIT and software Fluent will be used for the finite computation.
This paper presents a variant of a mathematical model of continuum mechanics. Adaption of the model is focused on the unsteady term. The solution is based on the assumption of the zero value of the divergence vector, which can have a different physical meaning. and Obsahuje seznam literatury a názvosloví
The article presents the mathematical model non-homogenous, isotropic environment, where is possible to create various types of flows (the chemical reaction flow, the diffusion flow, the heat flow, the electromagnetic flow). and Obsahuje seznam literatury
