Abstract

The paper presents a numerical study to investigate the effect of the viscous dissipation of laminar flow through a straight regular polygonal duct on the forced convection with constant axial wall heat flux with constant peripheral wall temperature. Both the wall heating case and the wall cooling case are considered. Applying the velocity profile obtained for the duct laminar flow and the energy equation with the viscous dissipation term was exactly solved for the constant wall heat flux using the Boundary Element Method (BEM). Nusselt numbers were obtained for flows having a different number of sides of a regular polygonal duct and Brinkman numbers.
