RISSuction Vortices in a Pump Sump—Their Origin, Formation, and Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The origin, formation mechanism, and dynamics of suction vortices in a pump sump have been clarified by large eddy simulation (LES) applied to two different computational models. The first one is a pump-sump model with ...
Large Eddy Simulation of the Rotating Stall in a Pump Turbine Operated in Pumping Mode at a Part Load Condition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The investigation of the rotating stall phenomenon appearing in the HYDRODYNA pumpturbine reduced scale model is carried out by performing a largescale large eddy simulation (LES) computation using a mesh featuring ...
