The studies which are presented here are computer simulations of fluid phenomena based on 2D lattice gas models of the kind first described by Frisch et al. (1986). The primary advantage of using these models is that they are easily implemented on massively parallel computers and as a result are extremely fast. / The first of these studies is of a model of phase separation in binary fluids. The growth laws of the fluid domains are examined and are shown to compare favourably to theoretical predictions of San Miguel et al. (1985). This appears to be a first verification of these results. The second study is of the critical behavior of a system of binary fluids. The model is shown to have a phase transition and the critical temperature is determined with an accuracy of 1%. Several critical exponents are also determined and evidence is provided that the model falls into the 2D Ising model universality class. A new model of fluid convection is also presented though no concrete results are yet available for this model.
