Abstract

This work describes a computational method to predict DA of particles with rough surfaces. A set of model objects having DS varying from 2.00-2.55 was constructed [4]. The DS was determined from Richardson's plot (log perimeter versus log yardstick). From these objects, all the parameters required to compute shape and surface roughness factors required to calculate the drag coefficient can be obtained.
