Abstract: The fully developed laminar heat transfer to non-Newtonian fluids flowing in a concentric annulus with a moving core is analyzed by taking into account the viscous dissipation of the flowing fluid. Applying the shear stress described by the modified power-law model, the energy equation together with the fully developed velocity profile is solved numerically for the thermal boundary conditions of the tube walls being kept at constant but different temperatures. The effects of the flow index, the relative velocity of the moving core, the dimensionless shear rate parameter and the Brinkman number on the temperature distribution and Nusselt numbers at the tube walls are discussed.
