RISDynamic Characterization of Vortex Structures and Their Evolution Mechanisms in a Side Channel Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To obtain a better insight into the unsteady flow behavior in side channel pumps by a robust vortex identification method, this study presents the efficacy of the new Ω-criterion in characterizing the evolution of vortex ...
Effect of URANS and Hybrid RANS-Large Eddy Simulation Turbulence Models on Unsteady Turbulent Flows Inside a Side Channel Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, the unsteady Reynolds-averaged Navier–Stokes (URANS) and three hybrid Reynolds-averaged Navier–Stokes-large eddy simulation (RANS-LES) models are employed to resolve the vortical flows in a typical single-stage ...
