Hi,

I planning to do simulation on ventilation and cooling systems. For my numerical simulation if I choose air as a working fluid which fluid should I use during experimental validation time(air or water)?Project proposal advice me to use air as a working fluid during CFD simulation but water should be used during experimental validation time, in here I am bit confuse, I prepare geometry and meshing on CFX as per experimental setup specification but in CFX pre if I choose air as working medium then air inlet velocity to the domain in simulation will be not same as water velocity in the experimental testing tank.How can I compare different parameter based on air data with same as from water data.

Could anybody suggest me in this regards.

Thanks in advance.
