摘要

The paper addresses a mixed convection boundary layer flowing on a horizontal surface embedded in porous medium with exponentially decaying internal heat generation (IHG) and internal mass generation (IMG) from a specific component with chemical reaction in order to investigate the heat and mass transfer characteristics. Corresponding similarity solutions are used to reduce the governing partial nonlinear differential equations to three ordinary differential equations for the dimensionless stream function, temperature, and concentration with the following parameters: mixed convection parameter e, chemical reaction parameter.1, and Lewis number Le. The influences of these parameters on the velocity, temperature and concentration profiles, and Sherwood and Nusselt numbers are thoroughly compared and graphically illustrated. Computations are performed with a system of parameters using built-in codes in Maple. Media with and without IHG and IMG are compared with available open literature using graphs and tables and are found to be in excellent agreement.
