Impact of wavy texture and hybridity of nanofluid on heat transfer augmentation over the frustum of cone geometry

Abstract

In this article, the impact of water-based hybrid nanofluid on heat transfer characteristics along the wavy frustum of the cone is examined. We considered hybrid nanofluid containing and nanoparticles. Non-similar form of the constitutive equations is obtained by using an appropriate set of transformations and results are achieved by employing transformed into compact non-similar form and are solved by the famous numerically implicit finite difference scheme known as Keller-box technique. The influence of the hybrid nanoparticles? volume fraction, frustum of cone half-angle and the wavy texture parameters on the Nusselt number and skin friction are scrutinized and comparison is made between the wavy frustum of the cone and flat frustum of the cone through numerical data. It is observed that the rise in the truncated cone half-angle leads to an increase in skin friction and Nusselt number. Titania - water nanofluid has lower heat transfer rates as compared to copper-titania hybrid nanofluid. The increasing of the truncated cone half-angle enhances the heat transfer rates. Generally, the results established from this analysis can be used as a benchmark for improving the natural convection heat transfer performance along the frustum of cone wavy texture.

“…The chemical reaction process and its influence on the mathematical model of three-dimensional (3D) Casson nanofluid with attached Brownian motion, thermal radiation, and velocity slip over stretched sheet are discussed by Umar et al 32 Latest studies related to the chemical process with magnetized mixture fluid and hydromagnetic Reiner-Rivlin nanofluid are discussed by Khan et al 33,34 Iqbal et al 35 did work on carbon nanotubes and heat transport analysis with associated geometry of rotating and stretchable disk. Further they 36,37 worked on nanofluid along with chemical process and effects on the hydromagnetic convective flow attached with a vertical wavy surface. Ghaffari et al 38,39 made their recent investigations related to entropy generation with chemical reaction impact and transfer of energy by increasing thermal conductivity associated with powerlaw nanofluid.…”
