Abstract

We will discuss the motion velocity of temperature convection when a single spherical aerosol particle is considered ignoring the fluid inertia term of thermophoretic effect. The boundary conditions of the plate can also be divided into two conditions to be discussed, respectively, when the adiabatic temperature displays linear distribution. When the droplets get close to the plate, one of the boundary effects of plate is from the interaction between temperature gradient generated in the aerosol particles and plate, and the other is from the adhesion effect of the fluid stagnation. The boundary-point method is used to obtain the motion velocity of the thermophoretic velocity parameters in different particle thermal conductivity ratios, and particle surface properties of phase related to the separation parameters, when compared with each other and with the reflection method validation. Boundary effect of plane walls may reduce or increase the aerosol particle moving velocity of particles due to the relative distance between the surface characteristics of the aerosol particles, aerosol particles and the plate, and different and boundary conditions of the plate.
