Physics - Based Simulations for Fluid Mixtures

Physics-Based Simulations for Fluid Mixtures Dongwoon Lee Doctor of Philosophy Graduate Department of Computer Science University of Toronto 2007 We develop a physics-based particle method to simulate various fluid mixture effects. A particle method is chosen over a grid-based method because we believe a particle method is more intuitive and better suited for handling physical and chemical interactions between fluids. Since a particle carries the physical attributes of the fluid (e.g, density and velocity), transfer of these attributes between particles can be computed easily using a particle method. Also, arbitrary shapes of the fluid mixture can be modeled based on the particles’ spatial configuration, which is updated throughout the simulation.
