Default central, upwind, UTOPIA, staggered grids

Posts: n/a
I am looking for good reference for convection terms discretisation and stabilization methods, mean about comparison of central differences, upwind (on staggered grids). I work with incompressible, free surface flows (SIMPLE, MAC).

Hope to get some reply this time..

Best Regards, Maciej Matyka

Hi there,

Check the work of Morinishi et al. (Journal of Computational Physics, 2 articles: 1998 and 2004).

The purpose of these 2 articles is to show that if you use a Kinetic Energy Conservative Scheme (it is possible to do so with the staggered mesh scheme), then you don't need any dissipation (or a dissipative scheme) to stabilize the code!! This is of great importance when you deal with turbulent flows (for example using LES modeling) since even the slightest amount of dissipation has a negative impact on the solution.

If hope this helps. Sincerely,

Frederic Felten.

Ok, will try this, it will be interesting to have solution without any stabilisation procedures.

Thank you.
