resistance in fan duct
 

hello everyone , can anyone tell me how can I put resistance in the downstream of the fan duct in order to calculate the pressure rise across the fan. My objective is to get the fan performance curve if is there any other way then kindly let me know. I am working with extruded duct across the fan with mass flow inlet, pressure outlet and giving fixed rotational speed to the rotating region(fan)

On the same problem at present. Did you find a solution after?

yes, I use inlet vent BC at the end of the outlet duct which was acting as a resistance by applying the loss coefficient values.

Thanks

Hashim, I ended up doing something similar. Have a 0 total pressure inlet and a X static pressure outlet. Cheers, John
