Several Studies On Simulating Boiling Water Based On Particles

Fluid simulation is an important branch of computer graphics, which has been widely used in lots of areas, such as the special effects in film and television, military simulation, animation and medical area etc. How to find more efficient models to simulate real fluid more rapidly and effectively is meaningful and very impotent.Chapter 1 introduces the background and significance of fluid simulation method, the research significance and research status inland and abroad.Chapter 2 mainly introduces the SPH and PBF method which are popular in fluid simulation at present, and briefly summarizes several improvements for the SPH method.Chapter 3 introduces the heat conduction model, the bubble model and the steam model in detail. The heat transfer model in tradition transfer heat through mesh, which needs huge calculation and its heat distribution is discret. This thesis presents a new method to conduct heat-transferring model by the smooth nuclear function in the SPH method, and the method is continuous in heat distribution and computes faster, and fits the realistic scenarios moreover.Chapter 4 first presents a concept of effect accuracy of particle in the SPH and PBF method which indicates the influence degree to the simulation effect with propties of particles, and therefore reduces the calculation and speeds up the simulation.Chapter 5 implements the model given above with VC++ language, and analyzes the simulation results obtained.Chapter 6 gives a summary of this thesis and some thinking and outlook of the future research of fluid simulation.
