Abstract:

simulation numerical of mass transfer from a neutrally buoyant particle in simple shear flow indicate in the paper. This article presents the numerical results for mass transfer at finite Reynolds and Peclet numbers. The simulations include solid-liquid mass. In this approach, liquid-solid interaction was successfully simulated using smoothed profile method (SPM). We solve a convection-diffusion equation for the solute concentration in the liquid using LBM. The simulations indicate that fluid particle in the flow-gradient plane spiral toward the particle for different Reynolds numbers. Comparing results with the ones presented in the literature shows good agreement. At low peclet number, the Sherwood number approaches increase with - (log Pe)-1 for the cylinder. Simulations at finite Reynolds numbers and Peclet numbers confirm the theoretical predictions for the concentration gradient at the particle surface.
