Entropy-generation analysis for variable-viscosity channel flow with non-uniform wall temperature

Applied Energy, 2008, vol. 85, issue 5, 384-393

Abstract: This paper is an analytical study of inherent irreversibility in the flow of a variable-viscosity fluid through a channel with a non-uniform wall temperature. It is assumed that the channel is narrow and the fluid viscosity varies linearly with temperature. Analytical expressions for fluid velocity and temperature are derived and employed to obtain expressions for volumetric entropy-generation numbers, irreversibility distribution ratio and the Bejan number in the flow field.
