Abstract
In order to simulate the ventilated-supercavitation flow more accurately, a local homogeneous medium model based on the state equation is proposed and embedded in commercial software. The two-phase flow model in the commercial software and the software+local homogenous medium model are used to simulate the ventilated-supercavitation flows around a disk-cavitator respectively. The simulated results are compared with the experimental data on bubble shape, flow structure, drag characteristic and so on. Since the local homogenous medium model considers the compressibility of the gas-liquid, it can simulate the ventilated-cavitation more acculately, and the bubble shape and the drag force coefficient computed from the model are more accordant with the experimental results.
