2D Transport of a Passive Scalar with OpenFOAM

15.3.15 Posted by Florin 1 comment
All the posts that have been written until now tackled the shockTube problem and the 1D transport problem; we've seen the convection and diffusion at work and we saw that there are a lot different schemes for divergences modelling. In the following I will show the setup and results for 2D scalar transport...

Modelling Convection in OpenFOAM

14.3.15 Posted by Florin No comments
As you may know by now, the Navier-Stokes equations are composed from three parts: a time component, a convection component and a diffusion component. The time component accounts for the change in time of the given scalar or vector; the convection component accounts for the transport of the scalar due...
