RISAssessment of an Improved Delayed X-LES Hybrid Model for the Study of Off-Design Conditions in Centrifugal Pumps
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Centrifugal pumps work in a wide range of conditions, often far from the design condition. The flow field can be characterized by large separations, vortex dynamics, and, in general, unsteady turbulent phenomena. Strongly ...
Investigation of the Volute Effect on Performance of a Centrifugal-Pump Impeller With High-Fidelity Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. In this work, the Delayed eXtra-Large Eddy Simulation (Delayed eXtra-LES) model is assessed for the simulation of the flow through a centrifugal pump, consisting of impeller, diffuser, and volute, both at design ...
