Two-dimensional laminar boundary-layer equations of momentum, heat and mass transfer have been numerically solved under forced convection. A finite difference approximation of the governing equations in a Gertler-type variable domain has been implemented on computer. To provide rigorous initial conditions at x=0 in the boundary-layer code, differential equations governing heat and mass transfer in the stagnation region have been set up and solved numerically.
The effect of outer flow condition on skin friction as well as heat and mass transfer has been demonstrated. Results obtained made an improvement over past theoretical predictions based on analytical approximation, and agreed favorably with experimental data available.
