Diffusiophoresis force
WebFeb 1, 2012 · Because the diffusiophoresis effect diminishes at large Reynolds numbers, the η s values of those four curves of Fig. 9 decrease with the increase of Reynolds number as the fluid inertia gradually becomes the dominant force in determining the initial collection efficiency of particles. WebThe diffusion force and rate are calculated for the diffusiophoresis of a spherical particle in a binary gas mixture by solving the gas–kinetic equations. Two schemes of diffusiophoresis are considered: constant–pressure diffusion and diffusion of one mixture component through the other fixed component. The problem is solved by the …
