不同重度流体自由塌落的数值模拟

In this paper a numerical simulation method - Moving Particle Semi-implicit method (MPS), based on the lagrange description of particle motion, introduces interactions between different fluids and makes the models , simulation computing. The numerical simulation does a better implementation with the collapsed process and focuses on the study of fluid movement returning to the basic unit—— a particle, the kinematics and dynamics of particle being tracked in the course of natural transformation, tracking the various changes of particle movement and thus acquiring the information of the entire flow field, included the location, mass, momentum and energy information. Between the nuclear function of particle interactions, through the establishment of physical model, the gradient model and the diffusion model to discrete the control equations.
