SPH方法对气液两相流自由界面运动的追踪模拟
Numerical tracking of interface in multiphase flows with smoothed particle hydrodynamics
摘要
Abstract
Multiphase flows are common problems in hydrodynamics. In these problems the deformations of interface are hard to track with conventional numerical methods. In this paper, smoothed particle hydrodynamics method is used to solve the multiphase problem, combining with slightly compressible model. To control the shape of interface, XSPH method and Van der waal correction were used. A dam breaking case and bubble rising case were presented in order to validate the method. Compared to the experiment results or other numerical results, some good agreements were obtained. It is demonstrated that the SPH method can be easily used to track the deformations of interface in multiphase flows关键词
