Description

Drag coefficients' numerical results of spherical particles, irregularly roughened in shape and size as per Weaire-Phelan and Orthogonal lattice structures, at Reynolds numbers 2, 4, 6, 8. The particles’ roughness has been determined as per different definitions based on either the surfacial or volumetric characteristics of the particles, including the mean diameter concept. Results include total drag, skin friction drag and form drag.
