Okay. So I am slowly being introduced to some CFD modelling and stagnation pressure keeps coming up as one of the variables.
We are modelling coolers, which of course have a fan(s) that distribute the cool air.
What exactly are we saying if a fan has high or low stag pressure?
I looked it up on Wiki and others, but the definition is not all that clear to me. It says that Pstag is the pressure at a point of zero velocity.
So with that definition in mind, how does Pstag translate to fans?
What does it say qualitatively about the fan and its affect on cooling?
Thanks,
Casey
