Duan–Rach Approach to Study Al2O3-Ethylene Glycol C2H6O2 Nanofluid Flow Based upon KKL Model

Abstract

This work explains the cooling capabilities of ethylene glycol (EG)-based nanofluid containing aluminum oxide (Al2O3) as nanoparticles. Because of its enhanced thermophysical properties, Nanofluids are used in many application areas of mechanical and engineering in the form of nanofluid coolants such as electronics and vehicle cooling, transformer, and computer cooling. Depending on the heating and cooling systems, it is also used as an anti-freezing agent, which lowers the freezing point but enhances boiling point and temperature coolant. After using appropriate similarity transformation, the present Koo–Kleinstreuer–Li model for solving the boundary value problem (BVP) is tackled analytically. A comparison is made with a purely analytical approach by a modified version of the semi-analytical Adomian Decomposition Method (ADM), which is introduced by Duan and Rach (Duan–Rach Approach) and shooting technique. Analytical and graphical treatment of the flow regime is carried out, and the behavior of the leading parameters on the velocity, temperature, concentration profile with the behavior of physical quantities i.e., skin friction coefficient, local Nusselt number, and local Sherwood number are illustrated. This study confirms that, due to extraction in width the flow moves away from the lower plate whereas it moves towards near the upper plate and a rapid decrease in temperature is marked when alumina–EG nanofluids are taken into account.

Characteristics of Darcy–Forchheimer drag coefficients and velocity slip on the flow of micropolar nanofluid

“…Nazari and Sarafraz recently published a paper with their colleagues on the thermal properties of micropolar nanofluids. 18,19 Researchers [20][21][22][23][24][25][26][27][28] considering different aspects of MHD and nanofluid flow have shown their interests and drawn some useful behaviors of the above fluid. Furthermore, Shafiq et al [29][30][31][32][33][34][35][36][37] have investigated several aspects of flow properties considering various nanofluids.…”

Stability and statistical analysis on melting heat transfer in a hybrid nanofluid with thermal radiation effect

“…On the other hand, Ashorynejad and Shahriari 5 analyzed the natural convective hydromagnetic flow of a hybrid nanofluid in an open wavy cavity. Moreover, the Ag–CuO/H 2 O hybrid nanofluid rotating flow with its partial slip and radiation effects was investigated by Hayat et al 6 Other related and recent studies about hybrid nanofluids and nanofluids include those reported in Khan et al, 7 Pattnaik et al, 8 and Muhammad et al 9–11…”

A comparative note on the free convection of micropolar nanofluid due to the interaction of buoyancy and the dissipative heat energy

“…Furthermore, Rashidi et al 11 proposed the aforesaid flow pattern with the Navier boundary state and solved the problem employing the DTM-Pade, an approximate analytical technique. Several authors [12][13][14][15][16] have worked on the flow behavior of the nanofluids, imposing the thermophysical model, such as the KKL model and they have used both analytical and numerical techniques for the solution of the transformed model. In particular, they have proposed the homotopy analysis method, finite difference method, and Adomian decomposition method, and so on, in various engineering applications, such as pumps and engines, astrophysics, aerodynamics, nuclear physics, and so on.…”
