Calculation of Source Coeffcient in CFX
 

Dear Memebers, I am modleing a fan flow with a general momentum source is a sub-domain. I am using a fan with 300 mm OD and 90 mm Hub dia, RPM 2500 and flow rate 900 cfm.

I am stuck in calculation of source coefficient C and specified values of Uspec, Vspec and Wspec as mentioned in CFX user guide.

Can some one help in estimating these parametes.

Thanks a lot in advance!
