Effects of Stefan blowing on mixed convection heat transfer in a nanofluid flow with Thompson and Troian slip

Abstract

The combined effects of Stefan blowing and Thompson–Troian slip on mixed convection flow of a nanoliquid over a flat plate with first-order compound response are examined. In several industries and engineering sectors, nanofluid plays a vital role in augmenting heat transport properties. Moreover, nanoliquids are used in chemical manufacturing, cooling of electronic machinery, and biomedical disciplines. The fluids with slip consequences have a wide variety of applications. As the Thompson–Troian slip model permits the alteration of the amounts of slip close to the areas of elevated shear speed and shear anxiety, the effects of this slip model are examined in this article. Using appropriate transformations, the partial differential equations (PDEs) of the model are changed to ordinary differential equations (ODEs), and the reduced ODEs are numerically solved. This study has noteworthy effects on the flow, the heat transfer, and the accumulation transport characteristics. With a rise in the slip velocity and the critical shear rate, the fluid velocity increases, while the temperature field decreases for a rise in the velocity slip. It is also observed that when the Lewis number increases its value from 0.3 to 0.4, the heat transfer rate at the plate increases by almost 30.88%, and the accumulation velocity transport at the plate rises by 56.92%. Interestingly, dual solutions exist for some specific range of values of the relevant parameters. The results of this study will be of use to scientists and engineers to understand better the flow and heat transfer characteristics.
