RISPressure and Flow Rate Fluctuations in Single- and Two-Blade Pumps
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A comparative study on the highly unsteady flow field in single- and two-blade pumps is performed. Stationary pump characteristics, as well as pressure and flow rate fluctuations, are presented. Wall pressure fluctuations ...
Three-Dimensional Simulation of Highly Unsteady and Isothermal Flow in Centrifugal Pumps for the Local Loss Analysis Including a Wall Function for Entropy Production
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A local loss analysis (LLA) based on entropy production is presented for the numerical three-dimensional (3D) simulation of isothermal centrifugal pump flow. A finite volume method and a statistical turbulence model are ...
