“…The passive technique (Mousavi Ajarostaghi et al, 2022) provides an increase in the heat transfer by making structural changes such as addition of the extra equipment and using different heat transfer fluids. Researchers have generally focused on lots of ways such as twisted tapes (Gürsoy et al, 2022a(Gürsoy et al, , 2022b, baffles (El-Said et al, 2021), winglets (Promvonge et al, 2021), extended surfaces (Zaboli et al, 2021), porous materials (Chakravarty et al, 2021), coil inserts (Dinh et al, 2022), rough surfaces (Gürsoy et al, 2023), mono, hybrid and ternary nanofluids (Dezfulizadeh et al, 2022;Said et al, 2022;Sirine et al, 2022). For instance, rough surface, which includes dimpled fins (DFs), is one of the prominent passive techniques in the geometric improvement, and this phenomenon has been investigated by numerous researchers in the literature (Gürdal et al, 2022a(Gürdal et al, , 2022b(Gürdal et al, , 2022cSuri et al, 2022; Magnetoconvection characteristics Malapur et al, 2023) conducted a computational analyse on five different dimpled tubes (DT).…”

Purpose The purpose of this study is to analyse the magnetic field effect on Fe3O4/H2O Ferrofluid flowing in a sudden expansion tube, which has specific behaviour in terms of rheology, with convex dimple fins. Because the investigation of flow separation is a prominent application in performance, the effect of magnetic field and convex dimple on the thermo-hydraulic performance of sudden expansion tube are examined, in detail. Design/methodology/approach During the solution of the boundary conditions of the sudden expansion tube, finite volume method was used. Analyses have been conducted considering the single-phase solution, steady-state, incompressible fluid and no-slip condition of the wall under forced convection conditions. In the analyses, it has been assumed that the flow was developing thermally and has been fully developed hydrodynamically. Findings The present study focuses on exploring the influence of the magnetic field, nanofluid concentration and convex dimple fins on the thermo-hydraulic performance of sudden expansion tube. The results indicate that the strength of the magnetic field, nanofluid concentration and convex dimple fins have a positive effect on the convective heat transfer in the system. Originality/value The authors conducted numerical studies, determining through a literature search that no one had yet investigated enhancing heat transfer on a sudden expansion tube using combinations of magnetic fields, nanofluids and convex dimple fins. The results of the numerical analyses provide valuable information about the improvement of heat transfer and system performance in electronic device cooling and heat exchangers.

A microstructural slip analysis of radiative thermophoretic flow of ternary nanofluid flowing through porous medium

Slip flows play a vital role in the microsystems, such as micro-valves, micro-pumps, hard disc drives, and nozzles. As a result, this study aims to examine the micro-structural slip behavior of ternary nanoliquid flow past a stretchable surface. Linear radiation is included in the law of energy, whereas the law of mass treats thermophoretic particle decomposition. The nonlinear partial differential system is reduced to an ordinary differential system by executing the appropriate transformations. Using a shooting approach with the help of Maple software, the flow, heat mass transportation, and micro-rotation profiles are estimated numerically. The effect of varying parameters on the physical quantities distributions is discussed via graphical demonstrations. The presence of microstructural slip reduces the velocity and micro-rotation profiles, whereas the nanoparticle concentration and temperature increase. The incrementing thermal radiation values augmented the temperature distribution. The concentration field narrows due to thermophoretic constraints.

Numerical Analysis of an Unsteady, Electroviscous, Ternary Hybrid Nanofluid Flow with Chemical Reaction and Activation Energy across Parallel Plates

Despite the recycling challenges in ionic fluids, they have a significant advantage over traditional solvents. Ionic liquids make it easier to separate the end product and recycle old catalysts, particularly when the reaction media is a two-phase system. In the current analysis, the properties of transient, electroviscous, ternary hybrid nanofluid flow through squeezing parallel infinite plates is reported. The ternary hybrid nanofluid is synthesized by dissolving the titanium dioxide (TiO2), aluminum oxide (Al2O3), and silicon dioxide (SiO2) nanoparticles in the carrier fluid glycol/water. The purpose of the current study is to maximize the energy and mass transfer rate for industrial and engineering applications. The phenomena of fluid flow is studied, with the additional effects of the magnetic field, heat absorption/generation, chemical reaction, and activation energy. The ternary hybrid nanofluid flow is modeled in the form of a system of partial differential equations, which are subsequently simplified to a set of ordinary differential equations through resemblance substitution. The obtained nonlinear set of dimensionless ordinary differential equations is further solved, via the parametric continuation method. For validity purposes, the outcomes are statistically compared to an existing study. The results are physically illustrated through figures and tables. It is noticed that the mass transfer rate accelerates with the rising values of Lewis number, activation energy, and chemical reaction. The velocity and energy transfer rate boost the addition of ternary NPs to the base fluid.
