Describe processes represented by the model Many 2D flow situation with simple boundary conditions (ie no inflow or outflow). suitable for lock/exchange simulation of gravity/turbidity currents or to study stability properties of stratified flow.
Describe key physical parameters and equations Incompressible flow equations: Navier-Stokes with Boussinesq approximations. Transport equation to describe the motion of particles (or Salanity or Temperature).
Describe length scale and resolution constraints Since we are doing DNS, we are restricted to low Reynolds numbers. Up to ~50,000 or possibly higher but very slow.
Describe time scale and resolution constraints
Describe any numerical limitations and issues
