Flow EFD type of k-e

MarkKeown · June 12, 2014, 04:42

Is Flow EFD / Flow Simulation using the "revised k-e" or the "standard k-e" turbulence solver?

Application is building aerodynamics and it is recommended to use the "revised".

Hi Mark,

FloEFD is using a modified k-e model.
What exactly are you trying to simulate?
I know FloEFD is used in HVAC applications but they range from HVAC ducts and units to room simulation.

Thanks for the reply.
In this application working on building aerodynamics and was looking at a 'best practice guide' that specified the k-e type.
Building aerodynamics is the flow of air around the outside of buildings and determining if the building design creates air velocities that are hazardous.

Ok, I understand. I don't think that should be a problem for FloEFD.
