As titiled, how to find the air flow rate (CFM or m^3/s) and static pressure(mm^2/H20) of a fan? I have already set up the simulation model, just confused on how to find the result.
If there is anything wrong in the setup please point out as well.
Have not looked at your file as I am responding through mobile. But traditionally if you are designing a fan, you use a rotating region to drive the flow and then either force a pressure difference from one side to another an measure the flow or reverse the problem. Goals are the usual way to output.
eh..pressure difference of the two faces of rotating region? or the entrance face and exit face of the fan? i did set up the rotating region,however, not sure how to find the pressure difference or the air flow rate. Could you point out specifically in my design how should I out them?
normally the testing is done in a tube or similar
so your measuring points and boundary conditions would be on each end of the tube
In the file I attached, I did put the model in a tube and set the both sides of the tube with environmental pressure. But still, I have no idea how to set the goals to achieve finding out the air flow rate and the static pressure.
let's look at it this way
if you were going to do this test in the "real world" how would you do it?
traditionally the way i've seen it done, you put the fan in a "wind tunnel" type assembly where you can measure pressure on both sides
you start the fan and run it and measure
this is the same thing you do in flow
make a tight tube around it
lids at both ends of environmental pressure
put goals for flow rate and pressure on both
setup your rotating region
run the analysis
