Turbulence Modeling in Smoothed Particle Hydrodynamics Methodology: Application in Nozzle Flow

Abstract

This work is an initial attempt to develop a Smoothed Particle Hydrodynamicscomputational method able to simulate turbulentfluid flows. The methodology is applied for modeling the flow field in the nozzle injector of action hydraulic turbines. Several turbulencemodels were implemented and their performance is compared with the Volume of Fluid continuous method and with corresponding measurements in a Laboratory model.
