“…Interfaces are ideal templates for assembling nanoparticles into structures by the nature of the interfaces. Interfacial layering or nanolayer refers to a phenomenon at the liquid-particle interface where liquid molecules are more ordered than those in the conventional fluids; therefore, the interface effect could enhance the thermal conductivity by the layering of the liquid at the solid interface (given that crystalline solids possess much better thermal transport that liquids) [193][194][195], by which the atomic structure of the liquid layer is significantly more ordered than that of the conventional liquid. At the interfaces, the nanostructures are mobile, and defects could be eliminated [196].…”

Progress in technology and industrial developments demands the efficient and successful energy utilization and its management in a greater extent. Conventional heattransfer fluids (HTFs) such as water, ethylene glycol, oils and other fluids are typically low-efficiency heat dissipation fluids. Thermal management is a key factor in diverse applications where these fluids can be used, such as in automotive, microelectronics, energy storage, medical, and nuclear cooling among others. Furthermore, the miniaturization and high efficiency of devices in these fields demand successful heat management and energy-efficient materials. The advent of nanofluids could successfully address the low thermal efficiency of HTFs since nanofluids have shown many interesting properties, and the distinctive features offering extraordinary potential for many applications. Nanofluids are engineered by homogeneously suspending nanostructures with average sizes below 100 nm within conventional fluids. This chapter aims to focus on a detail description of the thermal transport behavior, challenges and implications that involve the development and use of HTFs under the influence of atomistic-scale structures and industrial applications. Multifunctional characteristics of these nanofluids, nanostructures variables and features are discussed in this chapter; the mechanisms that promote these effects on the improvement of nanofluids thermal transport performance and the broad range of current and future applications will be included.

“…Hybrid nanofluids have been found to have streamlined qualities, demonstrating them to be appropriate for the heavenly bodies that require great warm, optical, and rheological attributes of working liquid. Flow caused by Al 2 O 3 water based nanofluid by shrinking cylinder in present of slip conditions was examined by Rana et al 24 by following Buongiorno's model. Esfe et al 25 explained that hybrid nanofluid have better influence on thermal conductivity than single particle nanofluids.…”

The objective of the current analysis is to implement the Cattaneo Christov heat (Non-Fourier’s) and mass flux (Non-Fick’s) concept in modified Buongiorno’s model for nanofluid magneto-transport phenomena over an extending cylinder in presence of gyrotactic microorganisms. The nanofluid comprises chemically reactive hybrid nanoparticles (Ag MgO Np’s) in the base fluid and Stefan blowing effect along with multiple slips is taken into account. The experimental correlations with their dependency on nanoparticle concentration are used for viscosity and thermal conductivity. The appropriate similarity transformations are applied to convert the PDE’s into non-linear ODE’s along with boundary conditions, prior to being evaluated computationally utilizing the Galerkin Finite Element Method (GFEM). The mesh independent test with different boundary layer thickness (ξ ∞) has been conducted by taking both linear and quadratic shape functions to achieve a optimal desired value. The numerical outcomes are in acceptable concurrence with those acquired from the literature. The results are calculated for realistic range of physical parameters. The warmth exhibitions are assessed through renowned Buongiorno’s model which effectively reflects the significant highlights of thermophoresis parameter(Nt = 0.001 to 0.05) and Brownian motion parameter (Nb = 0.001 to 0.05).

The present article addresses melting heat transmission phenomenon in MHD nanofluid flow between two horizontally located plates in rotating structure. This exploration is executed in engine oil-based nanofluid accompanied by graphene oxide nanoparticles. Thermal conductivity of the nanofluid incorporated with effect of diameter of graphene oxide and solid-liquid interfacial layer has been engaged here. Non-linear radiation is added in accepted nanofluid model. Through similarity technique, we obtain non-linear ODEs from leading PDEs, and numerically, by employing RK-4 shooting practice, we resolve the succeeding equation. Stimulus of inspiring flow factors on the flow specifically is accomplished precisely through figures and charts. Temperature circulation enhances with nanoparticle diameter and interfacial layer factors. Primary and secondary velocity outlines are reverse in nature when melting factor enhances.
