Buoyant plume source

Iona Evans

Hi, I'm modelling buoyant plumes in CFX by various methods. I have successfully generated a plume by simply creating a source point or a volume with some energy coming from it, however I would like to try something more complicated, in order to compare results to a scientific paper by Baines (J. Fluid Mech. 1983 Vol 132 p.247).

An equation balances the quantities of Momentum Flux [m^4 s^-2], Volume Flux [m^3 s^-1], and Buoyancy Flux [m^4 s^-3] that you need to generate a 'pure' plume. I would like to input specific values for these parameters into CFX however I am aware that I'm limited to continuity or energy terms.

Can anyone suggest how I would manipulate the terms I have, or the input methods in CFX, to generate this 'pure' plume?

Many thanks, Iona
