摘要
We investigate amplification of thermophoretic and ponderomotive forces caused by renormalization of static fields in linear clusters of particles with scale separation. We found analytically the dependence of the forces acting on the particles in a cluster as a function of the number of particles in a cluster and material characteristics of the particles and the surrounding fluid. We analytically determined the velocity of stationary motion of particles, velocity distribution in a surrounding viscous fluid, and the thermophoretic force when the particles remain stationary due to the applied constraint forces.
