Modeling HEPA Filters in CFDesign using Head Capacity Curve

217 Views, 1 Replies

When trying to replicate the flow through a section of HEPA filter, since I don't know the permiability constant I am using the Head Capacity Curve function. I have pressure drop (in H20) versus Air Velocity (ft/min) and have converted the velocity to flow rate based on the area of the filter section my flow volume is through.

 

However, the pressure drop that results is approximately double what was input in the Head Capacity Curve. Any ideas as to why this happens?

 

Thanks
