Abstract
Motion of Particles in a dilute turbulent boundary layer on a flat wall was simulated numerically. Eulerian-Eulerian two-way coupled model was used. Thermophoretic force and Brownian diffusion effects were investigated on the depositions of fine particles in a turbulent boundary layer. Turbulence closure was achieved by Prandtl’s mixing length model. The set of equations was solved numerically by using finite difference method. Introduced particle diffusion term played a significant role in numerical convergence. The proposed two-fluid approach for evaluating the effect of different forces on small particle deposition from a turbulent flow over a flat plate produced similar finding compared to Lagrangian method and computationally less expensive.
