“…equation (23) shows the relation to formulating 4% MWCNT/water nanofluid [ 39 ]. In this simulation of a single-phase homogeneous nanofluid, density and specific heat are estimated using the Pak and Cho model (equation (24) ), and Xuan and Roetzel (equation (25) ), respectively [ 40 ]. While the Esfe et al [ 41 ] models, which were created for MWCNT/water nanofluid for the temperature variation of 25 °C–55 °C, are used to calculate thermal conductivity (equation (26) ) and viscosity(equation (27) ).…”

“…By using a finite difference scheme, they numerically detected the interaction of nanofluid flow, isentropic lines, and isotherms characteristics inside a square enclosure. Other contributions to this concept can be obtained in references [32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48].…”

The current study scrutinizes the impact of heat and mass transfer on the slip flow of a nanofluid in a rotating system, which is designed by two infinite parallel plates. The effects of a magnetic field, thermal radiation, and chemical reaction are also added to the flow system. Copper oxide (CuO) is considered the nanomaterial with drinking water as the base fluid. The governing partial differential equations are transformed into a system of nonlinear ordinary differential equations with the help of similarity transformations. These equations are solved analytically by employing the least square method (LSM) and the Galerkin method (GM). The results computed by these methods are compared with the numerical method such as the Runge–Kutta method of order four (RK4M). The extensive applications of LSM and GM in comparison with RK4M are also presented. Although the attained outcomes are in good agreement, the results obtained with GM are more accurate than that obtained with LSM. Moreover, the contributions of various fluid parameters on the velocity, temperature, and concentration of the fluid are discussed through graphs. Results reveal that the presence of slip in the boundary declines the fluid velocity. The rotational velocity is enhanced with the increment of the rotation parameter. The magnitude of the skin friction coefficient is reduced by increasing the nanoparticle volume fraction while it grows by rising the magnetic parameter. The Nusselt number shows an enhancement with nanoparticle volume fraction, and it yields a slight reduction by increasing the effect of a magnetic field.

“…These nanotechnology-based fluids, termed as nanofluids, have outstanding properties such as high thermal conductivity. Today, nanofluids are used to improve thermal performance in a wide variety of applications [1][2][3][4][5][6]. Recent research has proven that the use of nanofluids and coiled tubes concurrently may considerably increase the HTR [7][8][9].…”

The thermal-hydraulic performance of conically coiled tubes (CCTs) was investigated experimentally under constant heat flux boundary conditions in this study. The effect of several factors, such as the flow Dean number, coil torsion, and varied nanoparticle weight concentrations, on the flow's heat transfer coefficient and pressure drop was studied. Thermo-hydraulic performance was studied at 0.3%, 0.6%, and 0.9% volume concentrations (ϕ) of Al2O3/water nanofluid, a Dean number (De) of 1148-2983, and coil torsions (λ) ranging from 0.02 to 0.052. Results indicated that the heat transfer rates (HTRs) of CCTs increased when the coil torsion was decreased. According to the findings, the average heat transfer coefficient (havg) rises as De increases, while friction factor (ƒ) tends to decrease. The average increase in havg is 32% at lower De values and 26% at higher De values as the nanofluid concentration increased from 0.3% to 0.9%. The thermal performance factor (TPF) improved when λ lowered from 0.052 to 0.02.
