Effect of viscous dissipation on fully developed heat transfer of non-Newtonian fluids in plane laminar Poiseuille-Couette flow

Fully developed laminar heat transfer to non-Newtonian fluids flowing between parallel plates with the axial movement of one of the plates has been studied numerically with an emphasis on viscous dissipation effect. The fully developed velocity distribution is predicted by a modified power-law model and the heat transfer results are presented for the thermal boundary conditions of a constant wall heat flux at one wall with the other insulated. The effects of the flow index and dimensionless shear rate parameter of a modified power-law fluid, the relative velocity of the moving plate and Brinkman number on the temperature distribution and Nusselt number are discussed.
