Abstract Application of lattice gas automaton (LGA) to engineering will be examined by dealing with mixing of two component flow without chemical reaction in a simplified stirred tank. In mechanical engineering, it is important to know quality and accumulation rate of products which depend essentially on mixing of raw materials. Mixing is usually formulated by partial differential equations of conservation laws and empirical formulae, and solved numerically by derived finite difference equations. LGA will be capable of calculating the fine structure of time-dependent interfacial behavior mesoscopically, since this has advantages of describing pattern formation of mixture in detail and is good at parallel computation. Parallel computation must now be a selected issue to determine whether LGA is applicable to practical problems. Computing power intends us to approach complex flow by new concept. This means that days of pure fluid dynamics are over and chemical process, phase change, material behavior must now be taken into account. The present example can described as a numerically intensive parallel computing problem as far as the number of PEs is increased up to 32 in the present numerical experiment.
