Effects of heat transfer on dusty gas flow past a semi-infinite vertical plate with variable temperature is considered. The governing boundary layer equations for this problem are set up and non-dimensional governing equations are solved by an implicit finite difference scheme of Crank-Nicolson method, which is fast convergent and unconditionally stable. Gas velocity, dust particle velocity, temperature, skin-friction and Nusselt numbers are calculated numerically for various parameters and are shown graphically. It is observed that an increase in the mass concentration of dust causes a fall in the dusty gas velocity but an increase in the skin-friction.
