Ali Amiri Popular answer

Dear Seyyed Joneid Hasannejad,

The best way is to use the Wen-Yu, Ergun blended model which is based on the fluid porosity. The Ergun model is accurate for a media which particles porosity is low, and the Wen-Yu model is accurate when the porosity of the particles is hight.

Best Regards,

Ali Amiri
