چکیده مقاله:
Engineering interest in natural and ventilated cavities over submerged bodies and in turbomachinery has led reserchers to study and attempt to model large scale cavitation for decades. Comparatively simple analytical methods have been used widely and successfully to model developed cavitation, since the hydrodynamics of these flows 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. Through some of these complicating physics can be accommodated in simpler physical models, the ongoing maturation and increased generality of multiphase Computational Fluid Dynamic (CFD) methods has motivated recent research by a number of groups in the application of these methods for developed cavitation analysis. This paper focuses on the two recent cavition modeling and their merits iover methods.
