Effects of pin fins and vortex generators on thermal performance in a microchannel with Al2O3 nanofluids

Jin Wang et al.

Summary: This paper presents a comparative analysis of pin fins and vortex generators to determine their optimal cross-section shape and parameters. A novel combined structure is proposed to enhance the thermal performance of an integrated microchannel heat sink. The effects of nanoparticle diameter and volume fraction are investigated using Al2O3 nanofluid and DI-water. The results show that oval pin fins and the optimal vortex generator significantly improve the heat transfer and hydraulic performance of the heat sink.

Thermodynamic evaluation and particle migration of hybrid nanofluids flowing through a complex microchannel with porous fins

Yuling Zhai et al.

Summary: This study investigates the use of nanofluids and porous media in microchannels to reduce pressure drop and enhance heat transfer. Numerical simulations and analytical methods are used to evaluate the effects of porosity and hybrid nanofluids on flow and heat transfer. The results show that porous media can reduce pressure drop and enhance heat transfer, and nanoparticle migration affects heat transfer. The effect of thermophoretic diffusion is higher in micro-scale convective heat transfer.

Thermal transport analysis of six circular microchannel heat sink using nanofluid

Hassan Waqas et al.

Summary: The rapid growth of electronics devices in the late 20th century brought about a revolution in the electronics industry. However, the miniaturization and continuous operation of these devices often lead to overheating and reduced performance. To address this issue, it has become essential to incorporate effective cooling systems in device design. Nanofluids, with their excellent properties, have gained attention for their ability to efficiently cool devices and improve energy efficiency. This numerical study focuses on examining the surface temperature, heat transfer rate, thermal resistance, Darcy friction factor, and reliability of microelectronic chips in minichannel heat sinks, by utilizing TiO2/water nanofluids as coolants and comparing the outcomes with conventional water cooling.

Summary: This article investigates the use of horseshoe-shaped fins and perforated tape in a solar system to improve productivity and mixing efficiency. The selected modeling techniques were found to be suitable for turbulent flow based on the comparison with empirical data. The study shows that dispersing hybrid nano-powders can enhance heat absorption and thermal efficiency, but at the cost of increased pumping power.

Fractional analysis of Jeffrey fluid over a vertical plate with time-dependent conductivity and diffusivity: A low-cost spectral approach

Muhammad Usman et al.

Summary: The researchers developed two new algorithms, the linearized spectral method and the semi-discrete method, which were successfully applied to solve the nonlinear coupled differential equations of the fractional-order MHD Jeffery fluid model. By using emerging parameters as numerical variables, the highly nonlinear problems were converted into a set of linear equations, leading to conclusions related to the Nusselt number.

On the hydrothermal behavior and entropy analysis of buoyancy driven magnetohydrodynamic hybrid nanofluid flow within an octagonal enclosure fitted with fins: Application to thermal energy storage

Nilankush Acharya

Summary: Minimum entropy generation is essential for the effective operation of thermal storage systems. This study investigates the hydrothermal behavior and entropy analysis of magnetized Ag-MgO-water hybrid nanofluid passing through an octagonal cavity and circular cylinder. The research reveals that nanoparticle concentration and Rayleigh number increase entropy generation, while the magnetized number reduces entropy generation. Additionally, the study demonstrates the impact of different fin lengths on the flow.

Thermal analysis of buoyancy-driven flow in a square enclosure filled with porous medium

Abhinav Saha et al.

Summary: The present investigation explores thermal convection in square-shaped, porous enclosures and its dependence on cavity orientation. The fluid flow and energy transfer equations are solved using the finite volume framework, and the Darcy-Brinkman-Forchheimer model is employed for porous medium. The study covers a range of modified Rayleigh numbers and examines the flow pattern, heat transfer, and energy transport by thermal convection. The results show that the Nusselt number varies with the modified Rayleigh number and cavity orientation, with an increase in convection up to a critical inclination angle and a decline thereafter.

The optimum double diffusive natural convection heat transfer in H-Shaped cavity with a baffle inside and a corrugated wall

Soroush Eshaghi et al.

Summary: The study investigates the double diffusive natural convection of a hybrid Cu-Al2O3-water nanoliquid inside an H-shaped cavity with a baffle at the top wall. It examines the effects of Rayleigh number, Lewis number, and Buoyancy ratio on Nusselt, Sherwood numbers, and entropy generation, as well as the impact of baffle inclination angle and aspect ratio of the corrugated bottom rib on heat transfer performance. The results suggest that the geometry with a baffle angle of -60 degrees and no corrugation has the best Nu(avg), while the geometry with a baffle angle of +60 degrees and no corrugation has the best Sh(avg).
