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 difference marching technique. Variation of wall concentration and wall flux with respect to the plate length is studied. Influence of Prandtl number, plate temperature on particle deposition and wall flux is presented in graphical form. An already established self‐adaptive grid generation technique and variable grid size method are incorporated in the computer routine to get more accurate results. The nature of variation of particle concentration profile with respect to Prandtl number is found to be similar. For a cold plate it is observed that the wall concentration increases with decrease in Prandtl number.
