Abstract

Bubbles are generally gaseous pockets within a fluid system but voids in semi-solid materials have similar physical properties and are especially relevent to modelling strength and other materials properties. Tghe dynamics and growth of bubbles and voids are often diven by surface tension and due to interactions are not easy to characterise analytically. Numerical simulation is often the only viable means of studying interactions amongst a large set of bubbles of voids ina system. Simulating bubbles and voids in complex fluids and in material systems is however a challenging problem using conventional fluid dynamical methods. We are investigating use of discrete lattice systems as a fast computational alternative that can yield interactive time simulations for real time visualisation and rendering. Discrete lattice automata approaches are feasible for both desktop and tablet computer systems and we explore some opf the issues, approaches and computational technalogies that can be used to achieve interactive bubble simulations. We also discuss how data parallel computational tools such as Graphical Processing Units and other processing accelerators can speed up these numerical simulations.
