fan's characteristic curve input problem

lqy · March 8, 2017, 20:14

Hello guys, I am doing a simulation of heat sink with one fan in phoenics VR but I don't know how to input the fan's characteristic curve data. The fan's characteristic curve expresses the polynomial relationship between the pressure and volume flow rate of the fan. I tried to write the function with InForm into the "Fan" or "inlet" object, but I don't know what the variable name of pressure and volume flow rate in phoenics. Would you please help me? Thank you in advance.

Hi, the fan curve can be edited in the VR menu under Models. Turn "Fan Operating point" on and click on settings. You can then create a new fan and enter the data for volume flow rate vs. pressure drop.

Hello, RD-CHAM. Thank you very much for your reply. I have found this function in FLAIR model and have applied it to my case. It seemed that the simulation results fitted well with the experimental results. Thank you again for your help.
