Asymptotic formulas for the forces and torques of two close particles in a Stokes fluid

Tóm tắt

The main goal of this paper is to establish the asymptotic formulas of forces and torques exerted by two closed spherical particles with prescribed velocities moving in a viscous fluid. Our proof is based on the decomposition into some more simple motions after a singular-regular decomposition of forces (torques) in the inner and outer region of expansions.
