خلاصه مقاله:
Engineering interest in natural and ventilated cavities over submerged bodies has led researchers to study cavitation.Comparatively simple analytical methods have been used to model the developed cavitation for flows whose hydrodynamics are often dominated by irrotational and rotational inviscid effects. However, a range of more complex physical phenomena are often associated with such cavities, including viscous effects, unsteadiness, mass transfer, three-dimensionality, and compressibility. In this study, cavitating flow over a two-dimensional wedge is simulated via a simple proposed cavitation model and large eddy simulation as turbulence. The governing equations are the unsteady incompressible viscous Navier-Stokes equations. The proposed method includes the combination of a source and a sink of vapor through a dissipation term. The comparison between the obtained numerical results and the Experimental data shows that the cavity characteristics are well simulated.
