- 論文の詳細を見る
The present paper is an extension of the previous study on fully developed laminar heat transfer of modified power-law fluids in a concentric annulus with an axially moving core and deals with the case for the boundary conditions of constant heat flux at the fixed outer tube with the moving core insulated. Applying the shear stress described by the modified power-law model, the energy equation including the viscous dissipation term is solved numerically. The numerical results are presented graphically for temperature profiles and Nusselt number at the outer tube with a number of parameters such as viscous dissipation effect, rheological properties and the boundary conditions. The effects of radius ratio, the flow index, the relative core velocity, the dimensionless shear rate parameter and Brinkman number on the temperature distribution and Nusselt number are discussed.
