This study describes numerical approach for adhesion behavior of micro-particle to a duct wall in gas-solid two-phase turbulent flow in a horizontal duct. Flow field was simulated by low Reynolds number k-ε turbulence model to estimate turbulence boundary layer accurately. The particle trajectories were simulated by means of Lagrangian method. The turbulence fluctuation component of fluid velocity was sampled randomly from the Gaussian probability density function based upon turbulence energy. The particle equation included wall- and shear-induced lift and rotary lift to estimate those effects to the particle adhesion behavior near wall region. It is assumed that the particle will stick to the surface when a particle once contacts to the wall. By the introduction of particle-wall collision model, the effect of particle collision angle on particle adhesion was considered. The simulation result for the particle deposition rate reasonably agrees with the experimental and simulation result of the other researchers.
