Heat Transfer and Transport Aspects of a ZnO/Ethylene Glycol-Water Nanofluid Through a Nonlinearly Stretching Sheet

Abstract

This section proposes investigating the heat transfer and transport phenomena of nanofluid passing through a non-linear stretching sheet. The 50%:50% water-ethylene glycol mixture is accepted as a base fluid to prepare a nanofluid. The influences of viscous dissipation, Joule heating, and thermal radiation in modelling are further exerted into attention. For converting partial differential systems to ordinary systems, a transformation technique is adopted. For the validation part, the numerical solution is computed by embracing a fourth-order exactness program (Bvp4c) and compared to the previously published literature. When modest quantities of zinc oxide nanoparticles are introduced to a mixture of water and ethylene glycol (EG), the effect on heat transfer relative to the base fluid is also noticeable. Furthermore, the influence of flow rate change in nanoparticle concentration on heat transfer performance is investigated. Graphical decisions reveal the values of miscellaneous-arising parameters on the velocity, temperature profile. The heat transfer rate is higher for the non-linear stretching surface than the flat surface. In comparison to nanofluid, a mixture of ethylene glycol-water with ZnO nanoparticles has superior cooling capability than the ZnO/water nanofluid.
