Abstract

The present investigation aims analytically at considering the fully developed forced convection in a fluid saturated triangular porous channel, with imposed heat flux at walls. The flow in the channel defined by the Brinkman-Forchheimer-extended Darcy equation which includes the inertial and viscous terms. The generalized momentum equation, along with energy equation were solved by applying the accurate analytical solutions based on the Galerkin Integral Method. The results show the effects of Darcy number, viscosity ratio, and inertia force on velocity and temperature profiles.
