Özet

In this part of the study, we investigate the problem of hydrodynamically developed but thermally developing laminar forced convection of a power-law fluid in a plane duct when the viscous dissipation is included. The axial heat conduction in the fluid is neglected. Two different thermal boundary conditions are considered: the constant heat flux (HI boundary condition) and the constant wall temperature (T boundary condition). The combined and interactive influences of the power-law index and the Brinkman number on the distributions for the developing temperature profile and local Nusselt number are determined in the entrance region for the wall heating and cooling cases at T and H I boundary conditions.
