“…Recently, Luo and Pozrikidis 22 computed the resistance coefficients of translating and rotating spherical particles in an infinite fluid and near a plane wall by applying the slip condition both on the sphere surface and on the plane wall. Beyond the creeping flow regime, 3D flows past unbounded stationary and rotating slip spheres were numerically examined by Atefi et al 37 and Meigounpoory et al 36, respectively, in the low to moderate Reynolds numbers regime.…”

“…8–21. However, analogous results with slip effects when the solid surface is spherical are very scant and are mostly restricted to the zero Reynolds number regime 22–35 except the works of Meigounpoory et al 36, Atefi et al 37, and Kishore and Ramteke 38. Furthermore, in real‐life applications wherein the solid spherical particles interact with surrounding fluids, the effect of volume fraction becomes a crucial parameter in the design of those solid‐liquid contacting equipment.…”

Effects of slip velocity and volume fraction of slip spheres on the momentum transfer characteristics of assemblages of slip spheres are numerically investigated. The fluid slip along the surface of the sphere is considered by Navier's linear slip model. The dimensionless governing continuity and momentum equations are solved using a semi-implicit marker and cell method implemented on a staggered grid arrangement in spherical coordinates. The convection and viscous terms of momentum equations are discretized by means of the QUICK scheme and a second-order central differencing scheme, respectively. The present numerical solver is benchmarked via grid independence and comparisons with the existing literature values. Results were obtained over a wide range of pertinent dimensionless numbers such as the Reynolds number, volume fraction of the dispersed phase, and dimensionless slip parameter.
