air duct
 

Hi,

I simulate the flow inside the air duct. The air speed at inlet boundary is produced by fan. The air speed is 27.7m/s. The reference pressure is set to 101325Pa. When I read the results I obtain about 70Pa of pressure at inlet. I have the results from other simulation where for 13m/s at inlet they have obout 480Pa of pressure. Do You think that these difference is due to other reference pressure (fan pressure taken into account)..?

Best regards

Jarek
