Abstract: The study presents thermophoretic deposition characteristics of particles in duct air flow. The v2-f turbulence model and discrete particle model were used to simulate particle-air flow. After numerical validation, particle thermophoretic deposition with different temperature gradient and particle diameters were investigated and analyzed. It was found that thermophoretic force has obvious effect on deposition velocity for small particles (d p 10m ), while almost no effect for large particles (d p 10m ). Thermophoresis effect is obviously enhanced when temperature gradient increases. Besides, thermophoretic deposition is mainly caused by the dramatic temperature difference in temperature boundary layer.
