Pressure difference at INLET and OUTLET.
Hello
I have to find out pressure difference at INLET and OUTLET for flow through a rectangular duct. I am using pressure-outlet conditions. I check pressure values in reports > surface integrals > area-weighted average > pressure at inlet and outlet. Pressure at outlet comes 0 and inlet pressure comes out 64 kPa. And NET pressure comes out 32 kPa. So is NET pressure value the pressure difference ? Sent from my C2004 using CFD Online Forum mobile app |
The difference is 64 kPa (inlet - outlet).
The NET value is the area-weighted average for both surfaces TOGETHER, i.e., since both surfaces seem equal, (64 + 0)/2 = 32 kPa. |
