Fluid flow through granular beds 1937
WebApr 5, 2024 · Compared to small pores, the pores of a larger volume are more likely to become a part of the main flow pathways. Van der Linden et al. (2024) found that the most direct routes for fluid flow to pass through the random bead pack are constituted by the large pores and the throats aligned with the flow direction. This may be attributed to the ...

Obviously, for both loose and dense packings, decreasing the thickness of particles, i.e. the increase of d/H ratio, will increase the porosity. This effect, though it varies with the did ratio, was found in all our tests involving more than 30 e (d/H, d/D)-d/H relations (Zou and ...
WebAbstract. Computational formulas for the porosity of a bed are presented for ratios D/d ⩽ 3 of the diameters of the vessel D and grain d. The relationship between layer porosity and the ratio D/d, which was derived on the basis of experimental data obtained from a number of studies, is indicated. Download to read the full article text.
