Pressure Drop, Electronic Housing

John Ashton Jan 23, 2009 1:54 PM

I have a box with an air inlet (defined as inlet static pressure) and an outlet that will be a fan (defined as outlet fixed volumetric flow rate). I need to find the pressure drop at the outlet to determine the prospective fan performance. I can use surface goals at the inlet and outlet, and use those results for an equation goal to find the delta but:
The choices for surface goals are Static Pressure, Total Pressure, and Dynamic Pressure. Also the choice of Min, Max, Average, or Bulk Average must be selected.

I am somewhat confused as to the defintion/selection of correct goals to determine the pressure drop. Any help would be appreciated.

delta P is the difference between the inlet and outlet average static pressures.

I am in very similar situation. Did you ever get an answer to this? You would think that the documentation would explain all of these choices...???

Same here, i'm in a similar situation but want to be able to ran it in an environment where temperature could range in -30deg to 90deg C. Would this be posible with simulation 2011?
