On all graphs, results have been obtained with space steps
and with time step .
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...
