Hi all,
I want to simulate the flow of a heavy gas leak (transient, non reactive).

For starters I want to use one of the buoyant solvers but I am not sure how to define the different species i.e. N2, SF6...

Also, should I use: buoyantPimpleFoam, buoyantBoussinesqPimpleFoam or rhoReactingBuoyantFoam.

Detailed examples much appreciated

Thanks

I found a wonderful work:

Numerical modelling of gas dispersion using openFoam / (2016) by Savio Vianna

In this work there is a detailed explanation how to use the rhoReactingBuoyantFoam solver using the combustion/reactingFoam tutorial as a base template.

I'm going to try now!
