Numerical Simulation of Cavitating Flows with Ventilation Using Multiphase Navier-Stokes Equations, M.Sc. Thesis Sharif University of Technology ; Hejranfar, Kazem (Supervisor)
Abstract
In this study, the numerical simulation of natural and ventilated cavitating flows is performed. The algorithm employs the homogenous, multiphase Navier-Stokes equations with appropriate mass transfer terms.The base line differential equations system is comprised of the mixture volume, mixture momentum and constituent volume fraction equations. A three species differential formulation is considered for constituent volume fraction transport/generation of liquid, condensable vapor and non-condensable gas fields.The system of governing equations is discretized using a cell-centered finite volume Roe’s upwind scheme. Both laminar and turbulent cavitating flows are considered in this study. For...
