Modeling air flow through a heat exchanger

dvanb · May 15, 2014, 12:07

Hello,

Can anybody tell me if STAR-CCM+ has the capability to simulate the pressure drop and straightening of air flow due to passing through a heat exchanger? A customer would like to match my CFX analysis but I have not used STAR-CCM+. In CFX I create a subdomain and apply a momentum source that uses a porous loss model to calculate a pressure drop proportional to velocity in the flow direction. The loss is multiplied in the cross-flow directions to effectively eliminate transverse velocity. I use this to estimate flow distribution across a condenser for a given set of ductwork.

How could this be done in STAR-CCM+?

Thank you,

David

You can do porous media in STAR-CCM+, yes, along with energy transfer through them. This is very common in the automotive market with radiators/CACs/TOCs/etc.
