Hydrodynamic interactions of spherical particles in Poiseuille flow between two parallel walls

摘要: We study hydrodynamic interactions of spherical particles in incident Poiseuille flow a channel with infinite planar walls. The are suspended Newtonian fluid, and creeping-flow conditions assumed. Numerical results, obtained using our highly accurate Cartesian-representation algorithm [Physica A 356, 294 (2005)] presented for single sphere, two spheres, arrays many spheres. consider the motion freely as well forces torques acting on adsorbed at wall. find that pair this wall-bounded system have complex dependence lateral interparticle distance due to combined effects dissipation gap between particle surfaces backflow associated presence For immobile pairs we examined crossover several far-field asymptotic regimes corresponding different relations separation distances of...
