In the present study, the boundary layer flow of a Newtonian fluid between two parallel porous plates separated by a fixed distance is examined numerically. The influence of viscous dissipation and thermal radiation on the flow field and heat transfer characteristics is specifically considered. The mathematical model of the problem is developed using the governing equations of mass, momentum, and energy for a Newtonian fluid. Suitable nondimensional variables are introduced to convert the governing partial differential equations into coupled ordinary differential equations, which are solved using the finite difference method. A graphical discussion is used to discuss the physical properties of the Reynolds number, Darcy number, Hartmann parameter, Eckert number, Radiation parameter, Rayleigh number and Prandtl number. The variation of a velocity and temperature profiles for various relevant parameters is investigated using graphs.
