We remember that the 2D-Burgers equation is a non dimensional equation, and so, time steps which will be appears possess no dimension. The objectives are not to study a real physical flow given by the 2-D Burgers equation, we just visualize some results calcultated with two different Reynolds numbers and two different tranversal advection speeds. Equally, in this study, numericals methods are just a tool which are only use to solve the 2-D Burgers equation, and so, we don't make any study about the optimal grid, schemes stability etc...
