Buoyant Plume Modelling

jlp56 · February 11, 2014, 14:10

Hi

I am looking to model a heat source within a room. As a first step I thought I would see if I could produce a standard buoyant plume using buoyantBoussinesqPimpleFoam. I setup a simple mesh with a small source patch on the floor to act as my heat source and specified it as a fixed temperature (deltaT~100 compared with the ambient). The source itself shows a higher temperature in paraview but there is no sign of any buoyant flow from the source. Am I being overly simplistic in hoping this would possibly work?!

Cheers

P.S. I have checked the sign on my gravity term.

You know the hotRoom tutorials (with and without Boussinesq approximation)? What happens if you start from them using your modified solver?
