Impact of Interface Model on Simulation Results of a Radial Pump at Part Load and Shut-Off Conditions

Computational Fluid Dynamics (CFD) is a well-known tool for predicting and analyzing performance in a variety of engineering branches, including turbomachinery, allowing engineers to partially replace physical experiments with their virtual analog. Nevertheless, numerical analysis should be used car...
