Simulation And Appliciton Of Fluid-solid Mixture On Free Surface

Recently, there is a new method for fluid simulation, moving particle method. It is a meshless method, therefore it can give a good simulation for free surface of the fluid.Classical fluid model has three equations:mass conversation equation, momentum conservation equation and energy conservation equation. There has been a lot of particle method. We are interested in finite volume particle method, this method gives out the control volume of each particle first, then use the control volume to discrete mass conservation equation and momentum conservation equation.Particle method can also apply to compute fluid-solid mixture model. Old methods didn’t consider effects on fluid particles produced by solid particles. We develop old methods and apply finite volume particle method to compute the interaction between fluid particles and solid particles and their movement to simulate the mixture of fluid and solid on free surface. We consider the effect on fluid produced by solid particles when computing, it is more reasonable. During programming, We apply link-list search algorithm and ICCG(incomplete cholesky conjugate gradient method) to reduce computing time.The result shows that this method can give a realistic simulation on mixture of fluid and solid and the free surface.
