Stably Stratified Flow

A numerical simulation for steady stably-stratified flow over a two-dimensional backward-facing step with a Froude number of 16/9, a Reynolds number of 800 and a Prandtl number of 1.0 is performed using a newly developed thermal lattice-BGK model. Excellent agreement between the present results and those of previous studies shows that the lattice-Boltzmann method is an efficient simulation method for complex flow.
