Abstract
Based on the surface rejuvenation model, the average grown period relying on a more detailed picture of the periodic sublayer development in the wall region has been obtained. Attempt is to extend this model to capture the interaction effects of thermophoresis and turbophoresis on the particle transport in the non-isothermal turbulent boundary flow field. In order to simplify the estimate of convective drift velocity of particles within the residence time of a single eddy, the detachment of concentration dependence components from the particle momentum equation is reached by reconstructing the overall particle flux of the particle continuity equation. This procedure establishes a basis for the appropriate estimates of the diffusion and inertial mechanisms, and provides an analytical solution to connect the quantitative predictions of particle concentration development with the diffusive and convective flux of particles. During the average growth period of viscous sublayer, the physical trend of the modeling parameters has been quantitatively revealed in some extent. In comparison with available particle transport data, the calculated results of the particle deposition rate for the different ranges of the particle relaxation time are in general agreement.
