Problems solved by technology

However, simulations of miscible fluids are physically more complex than simulations of immiscible fluids
[0003] In the prior art, the simulation method of dealing with mixable fluids based on the phenomenon of Brownian motion diffusion can obtain a certain mixing effect, but it essentially considers that in multi-component motion, each component moves at the same speed at any point in time , so it cannot fully simulate the real physical conditions

Abstract

The invention provides a fluid simulating method and device. The method includes the steps that firstly, a mixed flow model is constructed; secondly, smoothed particle hydrodynamics (SPH) particles are constructed; thirdly, relevant information of fluid needed by the mixed flow model is processed in the mixed flow model through an SPH method; fourthly, information needed in fluid simulating is output according to a processing result in the mixed flow model. According to the fluid simulating method and device, the moving process of multi-component fluid can be widely and accurately simulated.

Description

technical field [0001] The invention relates to the technical field of computer graphics fluid simulation and rendering, in particular to a fluid simulation method and device. Background technique [0002] In the field of computer image rendering, the simulation of multi-component fluids has attracted more and more attention. Compared with single-component fluids, multi-component fluids can display more abundant motion changes and obtain better visual effects. In the motion of multicomponent fluids, compared with the phenomenon of non-miscible fluids, the mixed fluids can more flexibly exhibit various gradient color characteristics, such as suspensions or dissolved solutions, which are related to the rich surface, interface The immiscible fluids of are visually significantly different. However, the simulation of miscible fluids is physically more complex than the simulation of immiscible fluids. [0003] In the prior art, the simulation method of dealing with mixable fluid...
