Dear all,
I am looking for the constants used in Ergun's equation to estimate the pressure drop through a packed bed. In fact, I would like to find the adapted constants for different shapes and sizes of particles not only spherical particles but also when we have an irregular and non uniform particles in the packed bed.
I hope I was clear enough in my comment, otherwise do not hesitate for further details about my request.
Thank you in advance for your help.
regards,
Keep in mind that the Ergun equation is applicable in many type of beds if the effective particle diameter used in the equation is chosen as the equivalent diameter of the particles, which is the product of Sauter mean diameter and shape factor of the particles in the bed.
Regards.
@Vitalli Pertsevyi : thank you for your response and the shared documents.
@Mounir Bouaifi : thank you for your answer. I've read that the Ergun's equation does not account the wall effect and this is for D/dp
