Flow at an angle of incidence
1 Attachment(s)
I have a domain with the inflow of air at an incidence of 30 degrees.

I'm modeling the inlet as a opening with pressure and direction.

To specify the flow direction Im using the option of cartesian components and I'm specifying the components as follows:

X = -cos(30 [degree])

Y = -sin(30 [degree])

Z = 0

Please find attached an image showing only the inlets portion of the domain and this would throw more clarity over the description.

Could some one please let me know if this is the right approach to model the flow at an angle.

The inlet should be just a pressure based opening at atmospheric pressure and there is a fan sucking the air from it inside the domain which is modeled with a fan curve.

I need the angle of incidence because Im not actually modeling some louver like structures inclined at this angle located at the inlets.

Sounds OK. Is it working as you intend?
