P-Q Curves in CosmosFlow
 
Hi All

I am simulating a fan P-Q curves,I have built a chamber which has a fan on the inlet,an opening pressure at the outlet,a thread nozle at the middle of the chamber.After the calculation I read the pressure drop from inlet and outlet,and the volume flow rate at the inlet fan,and plot the P-Q curves.
But the simulatiom P-Q curves is very diferent from the P-Q curves given by vendor.What is wrong with my setting??
