Finite difference modelling of natural convection flow with thermophoresis

Deals with thermophoretic analysis in natural convection laminar flow over a cold vertical flat plate. The governing equations are solved by finite di fference marching technique. Variation of wall concentration and wall flux with respect to the plate length is studied. Influence of Prandtl number, p late temperature on particle deposition and wall flux is presented in graph ical form. An already established self-adaptive grid generation technique a nd variable grid size method are incorporated in the computer routine to ge t more accurate results. The nature of variation of particle concentration profile with respect to Prandtl number is found to be similar For a cold Pl ate it is observed that the wall concentration increases with decrease in P randtl number.
