摘要：
Two methods for solving non steady advection-diffusion equations are analyzed and applied to some examples. Two methods are compared: a fixed point iterative method and another one that is obtained from working with the matrixes A and B that result from the discretization of the laplacian and of the advection term, respectively. This second method has proved to be much more efficient and can be used for solving the Navier-Stokes and Boussinesq equations in different formulations, with large Reynolds numbers. The processing time was found to be considerable lower for the method with matrixes A and B than for the fixed point iterative method, for the examples studied.
