Original abstract

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

Czech abstract

CFD simulace spočívá v modelování dvoustupňového čerpadla v čerpadlovém a turbínovém chodu. Analýza proudění se zaměří na úhel nátoku na kapaliny na lopatky a lokalizaci případného odtržení. Tento přístup by měl přinést úpravy geometrie, které povedou k zvýšení hydraulické účinnosti. Výpočtový model byl vytvořen v preprocesoru GAMBIT a výpočet realizován v softwaru Fluent.
