Mesoscopic multiparticle collision dynamics of reaction-diffusion fronts.
A mesoscopic multiparticle collision model for fluid dynamics is generalized to incorporate the chemical reactions among species that may diffuse at different rates. This generalization provides a means to simulate reaction-diffusion dynamics of complex reactive systems. The method is illustrated by a study of cubic autocatalytic fronts. The mesoscopic scheme is able to reproduce the results of reaction-diffusion descriptions under conditions where the mean field equations are valid. The model is also able to incorporate the effects of molecular fluctuations on the reactive dynamics.
