Numerical Study of Particle Deposition in a Channel Flow with a Built- In Cylinder

Abstract:- Particle trajectory and deposition in a channel flow with a rectangular cylinder was studied numerically. The continuity and Navier-Stokes equations were discretized using finite volume method. The particle equation of motion including the stokes drag force was used for determining lagrangian particle trajectory. Effects of aspect ratio, blockage ratio and stokes number on particle deposition on the cylinder front side has been studied for Re=200 and compared with previous work. The results showed that changing aspect ratio has no effect on particle deposition but the increase of blockage ratio and stokes number increases the deposition efficiency on front side of the cylinder.
