Hi, I want modeling pressure drop through a fabric, an article suggest that take a fabric as porous domain in CFX and set a linear resistance and quadratic resistance. But my result had a huge difference in comparison of pressure drop of article results. Can anyone guide me about the value of volume porosity and loss model (directional loss or Isotropic loss?) and loss velocity type (True velocity or superficial?) and if directional loss, what is the setting of transverse loss should be?
