Present paper deals with estimation of particle deposition rate from natural convection flow through a parallel plate channel. Brownian diffusion effect is incorporated in addition to convection and thermophoresis. Variation of properties is taken into account by property ratio method. Effect of axial heating and wall step heating on thermophoretic velocity and particle concentration within the flow domain analysed. Governing equations are solved using finite difference marching technique. Higher uniform particle deposition is obtained for axial heating along with step heating of wall.

Abstract


Present paper deals with estimation of particle deposition rate from natural convection flow through a parallel plate channel. Brownian diffusion effect is incorporated in addition to convection and thermophoresis. Variation of properties is taken into account by property ratio method. Effect of axial heating and wall step heating on thermophoretic velocity and particle concentration within the flow domain analysed. Governing equations are solved using finite difference marching technique. Higher uniform particle deposition is obtained for axial heating along with step heating of wall.
