I've created a wind tunnel for a school project in SW and am trying to run a flow simulation to test the maximum achievable wind speed within the test section. I know the motor our group is going to use but can't find anything close to the size I need in the available axial fans section of SW. I've never done a flow sim using a fan before but I believe it will provide much more accurate results as opposed to simply setting an airspeed through the assembly. I've attached screenshots of the tunnel to try and help, thank you in advance!
Also, the screenshot shows I've tried setting the circular end of the diffuser as the portion of the fan where air is exiting. I've set the four sections in the front inlet to be where air enters the fan. Running an external flow sim with velocity goals in z-direction. Am I doing it right?
