摘要: Mixed convection flow and heat transfer in a vertical channel filled with composite porous medium using Robin boundary conditions is analyzed. The modeled the Darcy-Lapwood-Brinkman model. viscous Darcy dissipation terms are included energy equation. plate exchanges an external fluid. Both of equal different reference temperature fluid considered. governing equations coupled non-linear because inclusion buoyancy forces. solved perturbation method valid for small values parameter. However, restriction on parameter relaxed by finding solutions Differential Transform Method. effects various parameters such as mixed parameter, viscosity ratio, width conductivity ratio Biot numbers discussed. percentage error between differential transformation increases both unequal numbers.
