Pressure Drop Black Box

Please login with a confirmed email address before reporting spam

I am modeling a facility exhaust system at a plant in order to properly balance the system with new additions we are planning. In this exhaust system we have a filter bank where there is a pressure drop that is gauged so we always know what the exact pressure drop is.

I am new to COMSOL and thought a good way to model this would be to use a poros material and adjust my permiability and porosity until I matched the pressure drop that is measured. I was wondering if anyone would know of a better way to add in a pressure drop between two interfaces thats easier than adjusting a filter material.

The actual physics of the filter is not important nor is any interactions happening in the filter bank. This model is simply to balance the system so any method to acheive that pressure drop is viable in the model.
