Abstract

The unsteady laminar incompressible boundary layer flow due to a twodimensional slot jet on a flat plate at an angle of attack has been studied The unsteadiness in the flow field is due to the free stream velocity distribution or wall temperature concentration which varies with time The governing partial differential equations in primitive variables have been solved numerically using an implicit finitedifference scheme in combination with the quasilinearization technique The effect of the variation of the free stream velocity distribution with time is found to be more pronounced on the skin friction than on the heat or mass transfer The Prandtl number and the variation of the wall temperature with time strongly affect the heat transfer Similarly the Schmidt number and the variation of the concentration at the wall with time strongly affect the mass transfer Beyond a certain critical value of the viscous dissipation parameter the plate gets heated instead of being cooled
