“…In a recent experimental study, Shah et al 36 discussed the significance of waterbased nanofluid (Fe 3 O 4 ) for nano-coolant. Srinivasan et al 37 used engine oil-based nanofluid for heat transfer enhancement in the plate using (Fe 3 O 4 ) nano-particle. Afshari et al 38 studied heat transfer enhancement in finned shells and tubes using water-based nanofluid and they were employed (Fe 3 O 4 ) as a working nano-particle.…”

In present times modern electronic devices often come across thermal difficulties as an outcome of excessive heat production or reduction in surface area for heat exclusion. The current study is aimed to inspect the role of iron (III) oxide in heat transfer enhancement over the rotating disk in an axisymmetric flow. Water is utilized as base fluid conveying nano-particle over the revolving axisymmetric flow mechanism. Additionally, the computational fluid dynamics (CFD) approach is taken into consideration to design and compute the present problem. For our convenience, two-dimensional axisymmetric flow configurations are considered to illustrate the different flow profiles. For radial, axial, and tangential velocity profiles, the magnitude of the velocity, streamlines, and surface graphs are evaluated with the similarity solution in the computational fluid dynamics module. The solution of dimensionless equations and the outcomes of direct simulations in the CFD module show a comparable solution of the velocity profile. It is observed that with an increment in nanoparticle volumetric concentration the radial velocity decline where a tangential motion of flow enhances. Streamlines stretch around the circular surface with the passage of time. The high magnetization force $$0 \le {{\mathrm{m}}_{1}}\le 6$$ 0 ≤ m 1 ≤ 6 resist the free motion of the nanofluid around the rotating disk. Such research has never been done, to the best of the researchers’ knowledge. The outcomes of this numerical analysis could be used for the design, control, and optimization of numerous thermal engineering systems, as described above, due to the intricate physics of nanofluid under the influences of magnetic field and the inclusion of complex geometry. Ferrofluids are metallic nanoparticle colloidal solutions. These kinds of fluids do not exist in nature. Depending on their purpose, ferrofluids are produced using a variety of processes. One of the most essential characteristics of ferrofluids is that they operate in a zero-gravity environment. Ferrofluids have a wide range of uses in engineering and medicine. Ferrofluids have several uses, including heat control loudspeakers and frictionless sealing. In the sphere of medicine, however, ferrofluid is employed in the treatment of cancer via magneto hyperthermia.

One of the smallest and most efficient heat exchangers on the market is plate heat exchanger. The goal of this experiment is to assess the performance of methanol-water as a base fluid in a plate heat exchanger affects the heat transfer performance. For this study, Aluminium Oxide (Al2O3) nanoparticle was used in various ratios (0.25, 0.5, and 0.75 vol. %) in a base fluid (10 vol.% methanol & 90vol.% water) to prepare a nanofluid. At two different temperatures, such as 55and 60?C, with varying flow rates (2 to 8 lpm) and varying nanoparticle concentrations (0.25 to 0.75%), thermo physical characteristics and convective heat transfer studies were performed and the results are presented. Overall inference was that there was a notable enhancement in the hot side, cold side and overall heat transfer coefficient by the Al2O3 nanoparticle and methanol-water base fluid combination. It was noted that utilizing Al2O3/methanol-water nanofluid could significantly reduce the temperature gradient in the heat exchanger and improve the performance of heat exchangers. Maximum hot fluid coefficient of 4300 W/m2?C, cold fluid coefficient of 4600 W/m2?C and overall coefficient of 2200 W/m2?C were noted for 0.75 vol.% nanoparticle concentration and at a flow rate of 8 lpm.
