Given a Fortran code that solved for the characteristics of a laminar, transitional, and turbulent boundary layer, the problem was to modify the existing program to predict the boundary layer over a flat plate and sharp nosed axisymmetric cone with mass transfer as a boundary condition at the surface of the model. The surface of the model was maintained at a constant temperature, and only the cases in which air was the transferred gas were studied. To solve this problem the boundary layer was described by the standard boundary layer equations for continuity, momentum, and energy. Incorporating mass transfer as a boundary condition, the governing equations underwent the transformation of Probstein-Elliott and Levy-Lees. The resulting equations and boundary conditions were solved by finite differencing techniques for nondimensionalized velocity components and temperature at a finite number of nodes in the boundary layer field of flow.
