BOUNDARY-ELEMENT METHOD CALCULATIONS OF THE MOBILITY OF NONSPHERICAL PARTICLES - 3 - PARALLEL IMPLEMENTATION FOR LONG CHAINS

A boundary element formulation for implementation on computers with ma ssively parallel architecture, which allows calculation of particle dr ag and torque for particle agglomerates, is described. Shape factors f or long, linear chains of spheres translating through a quiescent flui d are calculated. These calculations show that the correlation present ed in an earlier paper (Geller et al., 1993), which was based on bound ary element results for much shorter chains, continues to hold for cha ins of up to 700 constituent spheres; and, as expected, the slender bo dy results, also presented by Geller and coworkers (1993), more closel y agree with the numerical results for these longer chains.
