COEFFICIENT AND INTERNAL FLOWS

A new theory of diffusiophoresis of large volatile spherical 
aerosol droplets, which is a further development of the previous 
investigations, has been formed. Account has been taken of the 
influence of the evaporation coefficient  of the droplet liquid, 
the surface-tension coefficient variable along the droplet surface, 
and internal flows in the droplet on the diffusiophoresis velocity. 
The formulas obtained enable one to directly find the velocity of 
motion of single large aerosol droplets in a binary gas mixture 
inhomogeneous in concentration.
