Effect of the Prandtl number and mass transfer on the unsteady incompressible boundary layers near the three-dimensional asymmetric stagnation point

Unsteady, three-dimensional asymmetric stagnation-point flow with an arbitrary velocity profile was examined for the effects of the Prandtl number on the heat transfer when dv/dt is continuous. Attention was given to mass transfer effects on heat transfer and skin friction in both saddle point and nodal cases. Solutions in the neighborhood of the stagnation point were obtained with a series expansion. Partial differential equations were then defined and solved with an implicit finite difference scheme. The maximum heat transfer was shown to occur away from the stagnation point because of an increase in boundary layer thickness. The Prandtl number and the wall temperature variations affected only the heat transfer, while the mass transfer influenced both the heat transfer and the skin friction.
