Abstract
This paper presents a numerical investigation on the effect of parameters like bed to particle diameter ratio, shape of the porous material, porosity and particle diameter by which the porous medium has been made on pressure drop. And the direct empirical correlations for the same are established. Core and annulus are the two shapes of porous medium considered for investigation which are more popular in literature. It is observed that all the three parameters show a positive effect i.e reduction in pressure drop when their values are increased. Further investigation shows that there is a critical bed to particle diameter ratio beyond which the effect of shape of the porous medium on pressure drop is negligible.
