Hi everyone I'm trying to model a conic filter in starccm+.
The infos i have about this filter are: porosity, flowrate, surface area and pressure drop through the filter.
I'm modeling it using the porous baffle media (shear stress based). How can i set the pressure drop to be exactly the one specified in the data sheet i have been given? I tried following the ansa help guide and Ergun equations but when i run the simulation with the numbers i found for Pi (porous inertial resistance) and for Pv (porous viscosity resistance), it gives me meaningless results.
Thanks in advance for any reply
