Diffusiophoresis assumes that the condensation of gaseous hydrocarbons creates a vapor concentration gradient, which provides direct transportation of particles to the wall surface.
The mechanisms that influence particle deposition on heat transfer surfaces include: impaction, gravitational settling, Brownian diffusion, electrostatic attraction, interception, diffusiophoresis, thermophoresis, and adhesion through van der Waals forces.
