Unsteady Jet Expansion

September 11, 2005, 22:48

Hi,

I'm a PhD student modelling the transient expansion of a jet into a region at significantly lower pressure. Has anyone done a simulation of this nature in the past? Also: is it possible to model a constant volumetric flow rate boundary condition in Fluent for a transient problem? At example would be using a rotary vane vacuum pump to evacuate a chamber.

Cheers

Hi Hadley, have you found out the solution? I am doing the similar case and really want to know how to model it. thank you.
