摘要: Combined free and forced convection flow in a parallel plate vertical channel filled with porous matrix is analyzed the fully developed region boundary conditions of third kind. The modeled using Brinkman–Forchheimer-extended Darcy equations. plates exchange heat an external fluid. Both equal different reference temperatures fluid are considered. Governing equations solved numerically by shooting technique that uses classical explicit Runge–Kutta scheme Newton–Raphson method as correction analytically perturbation series for model. velocity field, temperature field Nusselt numbers obtained governing parameters such parameter, inertia term parameter unequal Biot displayed graphically. dimensionless mean bulk also determined. It found numerical solutions agree small values absence inertial forces.
