The heat distribution on this motor is not normal, and the fan does not rotate as desired towards the motor.
link project = FAN NOT SPIN
Hey @366 ,
Thanks for posting on the forum.
The direction of axis specified for the rotating zone looks incorrect to me.
It is specified to be in +'ve Z direction, which means with right hand rule the rotation of the fan does not make sense, the axis of rotation should be the same as the fan axis, in this case, X direction. + or - depending on which direction you want the fan to rotate. See this part of the rotating zone article.
Other than that, MRF is an approximation of the rotating effects induced into the flow region that intersects with the assigned MRF zone. It does not actually move the blades of the fan.
Let us know if you need more support here!
Cheers!
Can’t MRF speed up the airflow directed to the motor?
MRF is used to approximate rotational motion within flow domain. If you want to simulate acceleration in flow because of a fan , you can define momentum sources instead and also specify by how much you want to accelerate the flow through this source body.
Cheers!
After I create a momentum source, how do I control the rotation speed of the air flow caused by the fan rotating at RPM?
