A spherical condensed phase (volatile particle) is placed in an infinite expanse of a binary mixture consisting of the vapor of the condensed phase and another noncondensable gas. The mixture is assumed to be at rest with uniform pressure and temperature at infinity. However, the vapor and the noncondensable gas have small uniform density (or concentration) gradients of the same magnitude but in the opposite direction. The flows of both components around the particle are analyzed numerically by a finite-difference method on the basis of a model Boltzmann equation for gas mixtures, and the force acting on the particle (diffusiophoretic force) is obtained accurately for a wide range of the Knudsen number. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR] |
