The Research Of Fluid Interaction Simulation

The simulation of nature phenomenon with graphics methods is always anEmphasis which is concerned by researchers of the computer graphics field. Thus theinteractive simulation of dynamic fluid research in this area is hot and difficult. It is acomplex fluid flow, the actual representation of this process must be based on themethod of process or physics. The method based on physical and the particle systemmethods are two modeling methods which can describe irregular objects, and capturethe details of fluid movement. So, they are used in fluid interactive simulation fieldincreasingly.When dealing with general flows , the method based on physical could reflectmore details of fluid movement, and could solve deformation problems,free surfaceproblems and interaction problems. Smoothed particles hydrodynamics is a theorybased on N-S equations, which could capture more complex phenomena of fluidmovement more expediently and more comprehensively. In the dissertation, the SPHrules discrete the N-S equations, and then a simulation method to interact with theembankment is presented .The results demonstrate that this method could identify thefree surface, also reflect changes in various details, such as moving process,spraysplashing and integration, impact with the embankment , free surface deformation,and so on.Systematic approach based on particle flow can be set as discrete particles, eachparticle has certain properties, the particle system is the modeling tool which theconstruction three dimensional scene must not be possible to lack. Particle systemtheory is the commonly used method to describe the irregular objects, therefore, Someresearchers trace their introduction to the stern of the simulation .In this article, in thefoundation which the predecessor simulates, we present particle system and thehydromechanics method, we successfully simulate the boat traveling in the water thanproduced more realistic wake effects, and we use particle system to simulate spraysplashing , also increase the system interaction.As is shown in the results, the two methods shown in this dissertation haveproduced satisfying results, which proved the superiority of methods based-onphysical moving rules.
