Theory of thermophoresis of nonvolatile liquid aerosol particles
Abstract
Boundary conditions for the stresstensor components at a gasliquid interface are derived and justified for the case in which gas inhomogeneity results from a temperature gradient, and the ratio of the mean free path (lambda) of the gas molecules to the radius of curvature (R) of the surface is small; the Knudsen number Kn = lambda/R is the small parameter. A complete system of boundary conditions at the drop surface is derived, which can be used to calculate the thermophoresis velocity of nonvolatile liquid drops of moderately large aerosol particles.
