V. Dolejs et I. Machac, PRESSURE-DROP DURING THE FLOW OF A NEWTONIAN FLUID THROUGH A FIXED-BED OF PARTICLES, Chemical engineering and processing, 34(1), 1995, pp. 1-8
A method is presented for the pressure drop calculation during the flo
w of a Newtonian fluid through granular beds based on an analogy with
a fluid pipe flow. Aspects affecting problems of flow around particles
are considered simultaneously. The usefulness of this method has been
verified experimentally in the flow of both incompressible and compre
ssible fluids through beds of spherical and non-spherical particles.
