“…Gum Arabic can be a promising surfactant for stabilizing the CNT in water-based nanofluids. Cacua et al [3] found Al 2 O 3 nanofluid with SDBS at 1 CMC and CTAB at 0.5 CMC were the most stable and unstable nanofluids, respectively. Anionic SDBS provides high repulsive forces between nanoparticles.…”

Both mono and hybrid nanofluids, the engineered colloidal mixture made of the base fluid and nanoparticles, have shown many interesting properties and become a high potential next-generation heat transfer fluid in various engineering applications. The present review focuses on improving the stability of the nanofluids. For this, the present review briefly summarizes the impact of nanofluid preparation on the stability of various nanofluids and described in the following classification; (a) Nanofluid constituent, (b) Nanomaterial synthesis, and (c) Nanofluid synthesis techniques which are well-grouped and thoroughly discussed. Physical mechanisms for heat transfer enhancement using nanofluids are explored as well. Most of the studies reveal that there are significant improvements in the stability of the nanofluids. Hence, there is an excellent opportunity to use stabled nanofluids in various engineering applications. Finally, some useful recommendations are also provided.

“…Various nanofluids have been explored for use in the closed two-phase thermosyphon, including bauxite/water [100], Al 2 O 3 /water [101], TiO 2 /water [102], graphene/water [100,[103][104][105], graphene oxide/water [106]. The effect of nanofluids on heat transfer characteristics of thermosyphon is complex.…”

“…The sediment layer can enhance the number of nucleation sites, whereas slurry sediments will decrease the half cone angle or mouth radius of the cavity and decrease the number of nucleation sites. Cacua et al [101] revealed that both the effect of the nanoparticle deposition and surfactant on the boiling heat transfer mechanism had to be taken into account to explain the improvement of THP thermal performance. Wlazlak et al [106] observed that graphene oxide nanofluids enhanced heat transfer of a thermosyphon at low heat loads and this enhancement was limited to the evaporator.…”

This research article aims to investigate the consequences of binary chemical reaction, thermal radiation, and Soret–Dufour effects on a steady incompressible Darcy–Forchheimer flow of nanofluids. Stretching surface is assumed to drive the fluid along positive horizontal direction. Brownian motion, and the Thermophoresis are accounted in particular. The governing highly nonlinear system of problems which are advanced version of Navier–Stokes equations are transformed into ordinary differential equations (ODEs) using appropriately adjusted transformations invoking symmetric property of the independent variables. The numerical approach using RK45 in connection with shooting technique is adopted to solve the final equations. Graphical approach is used to interpret the results and the values of important physical quantities are given in tabular data form. Velocity field, temperature distribution and concentration distribution are graphically analyzed for variation in respective fluid parameters. Furthermore, density graphs and stream lines are sketched for the present model. The outputs indicate a rise of temperature field in connection with thermal radiation parameter. A clear decline is noticed in velocity field for elevated values of Forchheimer number and porosity factor. The Dufour effect anticipates a rising factor for temperature distribution and the same is noticed for concentration distribution in lieu of Soret effect. Thermal radiation and binary chemical reaction has strong impact on heat transport mechanism. The results for physical quantities such as skin friction, heat and mass flux rates are given in tabular data form in last section of this study.
