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 ...
Description of Unsteady Flow Characteristics in a Side Channel Pump With a Convex Blade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To investigate the unsteady flow characteristics in side channel pumps, the vortex structures and their evolutions in the impeller and side channel flow passages have been comprehensively studied. Systematically, three ...
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 ...
