Numerical Modelling of Cavitating Flows in Venturi

摘要

The cavitation is one of the most binding physical phenomena influencing the performances of the hydraulic machines. This paper presents a theoretical study modeling of cavitation in cavitating flows and a numerical study of a cavitation pocket developing in a Venturi flow. The study of the flows by the digital present simulations CFD also has big interest. For the numerical simulation we used the free software to access the code and the algorithms. OpenFOAM is a toolbox for computational fluid dynamics.
