compute Richardson number using Fluent

dsanthosh2 · July 3, 2012, 05:40

Sir,
I want to compute Richardson no Gr/Re^2 at each and every grid node. I am solving supercritical fluid flow. therefore the wide change of properties like density, viscosity..which increases the buoyancy force. So I have to find each and every cell the value of Gr/Re^2. Could any one help how to find Ri value using Fluent. Thanks in advance.

Next time do a little bit of searching...

If you need to calculate Ri for postprocessing:
Just go to define - custom field function

then define the variable you want to compute.
