Fluid injection to a laminar boundary layer with variable wall mass and heat flux
Abstract
Simultaneous mass and heat transfer from a flat plate with uniform fluid injection and variable surface mass and heat fluxes is studied analytically. Local nonsimilarity velocity, concentration, and temperature profiles in the laminar boundary layers are obtained for unity Lewis number with Prandtl number/Schmidt number equal to 0.7 and 7.0, and over a range of fluid injection rate. The effects of injection rate and variations in prescribed wall mass and heat fluxes on the mass-concentration and thermal behavior of the flow are examined. Correlation of data for the Nusselt and Sherwood numbers are presented. Results are found in excellent agreement with published theoretical and experimental data for the special case of uniform wall heat flux with injection.
