This study concerns the heat transfer and entropy generation characteristics of viscoelastic fluid flow modeled by the exponential formulation of simplified Phan-Thien-Tanner (s-PTT) model. This is the first such study in literature of thermal behavior of viscoelastic fluids modeled by the exponential formulation of s-PTT model. The flow between two parallel plates is laminar, hydrodynamically and thermally fully developed, viscous dissipative and subject to uniform heat flux on the walls. The slip velocity boundary condition is imposed on the fluid-solid interface and the slip is captured by three slip laws, namely, Navier's non-linear slip law, Hatzikiriakos slip law, and asymptotic slip law. The governing equations have been solved analytically. Closed form solutions for the velocity distribution have been derived while the temperature distribution is presented in terms of an infinite but convergent series. The results pertaining to the three slip laws have been presented in detail. Finally, a comparison has been made between the results for exponential formulation and those for the linear formulation of the s-PTT model. The comparison shows that results for linear formulation deviate significantly from those for exponential formulation and thus the accuracy of the exponential formulation justifies the extra mathematical complexity which it entails. © 2015 Elsevier Ltd.

This paper is an analytical study of entropy generation in the laminar flow of nanofluids in a circular tube. The tube is immersed in an isothermal external fluid - which is the most general thermal boundary condition but has not been studied in much detail in literature. Two nanofluids, namely - water-Al2O3 and ethylene glycol-Al2O3 have been chosen for this study. The effects of the external Biot number, non-dimensional temperature difference and volume fraction on the entropy generation characteristics of the flow have been shown through graphs and the physical reasoning behind the observed trends has been discussed threadbare. It is shown that the addition of nanoparticles is beneficial only at smaller Reynolds number and for less viscous base fluids. Most importantly, it is proved that the entropy generated in the case of a tube immersed in an isothermal external fluid is bounded by those for uniform heat flux and uniform wall temperature boundary conditions. © 2015 Elsevier Ltd.

This paper investigates the effect of three-dimensional loading on macroscopic fretting variables, such as contact tractions, slip and contact stresses over the dovetail interface, carried out using three-dimensional finite element method with frictional contact at the interface. Three-dimensional loading effect is brought out by considering a skewed dovetail slot in the geometry and by application of forces and moments acting on the airfoil. The study reveals that a skewed (20°) dovetail experiences about 100% more peak contact pressure and slip amplitude than a straight dovetail slot. The peak contact pressure and contact stress are observed near contact edge, either at the leading or the trailing edge, for all the load cases studied for skewed dovetail. The contact traction, stress and slip variation along the dovetail are significant when compared with two-dimensional results. The study suggests that skew angle and three-dimensional loading need to be considered, for an improved understanding of the fretting aspects of a dovetail interface. © 2010 Elsevier Ltd.

This study deals with heat transfer and entropy generation analysis of pressure driven flow of a power law fluid in a microchannel. The microchannel is subject to uniform heat flux boundary condition at the walls. The slip at the walls has been modeled through three different slip laws, namely: non-linear Navier slip law, Hatzikiriakos slip law and asymptotic slip law. All the governing equations have been solved analytically. The effect of various friction coefficients of the slip laws on velocity distribution, temperature distribution, Nusselt number, entropy generation rate and Bejan number has been shown. The reason and the justification behind the trends observed have been discussed in detail. A comparison has been made between Hatzikiriakos slip law and asymptotic slip law with regards to Nusselt number and average entropy generation rate. It is observed that, for the same slip coefficients, the value of Nusselt number as predicted by Hatzikiriakos slip law is higher and average entropy generation rate is lower than the corresponding values predicted by asymptotic slip law; and this difference increases with increase in the value of slip coefficients. © 2014 Elsevier Ltd.
