Motivation
Current slope limiters have issues converging for incompressible and weakly compressible flow. Formulation should be revised and improved for incompressible and weakly-compressible flow.
Dispersion test case (adection of a scalar at 45 degrees)
Expected results: similar results in OpenFOAM
Design
For second order upwind, we suggest implementing the standard formulation as folllows:
where$\alpha$ is the parameter computed by the limiter.
Impact
These modifications could allow the usage of second order upwind for the finite volume formulation.
