  3. Abstract:
  4. The first and second laws of thermodynamics were investigated analytically for a two dimensional partially filled porous channel. The porous layer is attached to the channel walls in first test case and the second one is a fully filled porous channel. The flow is laminar and steady with constant wall temperature. New analytical solution for temperature, velocity, Bejan and entropy generation number profiles were obtained considering viscous dissipation effects. The results of our new analytical solutions were validated against the numerical results of the lattice Boltzmann method (LBM) which show very good agreement. Using these analytical solutions, detailed analysis of the effects of Brinkman number, Darcy number and the porous layer thickness on Nusselt, entropy generation and Bejan numbers were carried out for mentioned test cases. © 2024, Toronto Metropolitan University.
