I just want to share few knowledge on solving this type of
equation:

- It's preferable to discretize time by implicite scheme for
stability, at least for the laplacian (diffusion) term.

- The convection term needs to be discretized by "up-wind"
scheme, that warrants also the stability and ensures the
solution to satisfy entropy condition. The up-wind is more
tricky to implement in 2D than in 1D.

Good luck,

Bruno
