Abstract
Recently, the lattice gas method has been widely used to simulate fluid motions. Many researchers have computed the velocity fields of various flows by this method, and have already confirmed that the results agree well with the experiments. However, the pressure field has not been examined. In this paper, in order to verify the pressure field of the lattice gas method, we will present a method to compute the pressure field, and apply it to a flow around a plate and that around a rotating wing which is a model of the Weis-Fogh mechanism. The drag and the lift coefficients obtained by this method agree reasonably well with experimental values, and the validity of the pressure fields by the lattice gas method was confirmed.
