Summary: This work presents a numerical analysis of conjugate heat transfer in an annular channel with different working fluids to understand the impact of flow constraints and heat transfer. By comparing different turbulent Prandtl numbers, temperature fluctuation, and heat flux density, it was concluded that caution should be exercised when using existing models.

Summary: Nanomaterials, as potential biocompatible materials, offer extraordinary characteristics in various sectors of the food industry. The synthesis of biocompatible nanomaterials involves modifying their shape, density, and size. These nanomaterials are designed to reduce toxicity, minimize adverse effects in the gastrointestinal tract, and enhance immune response. They can target specific organs and interact effectively with functional foods and nutraceuticals. Applications of biocompatible nanomaterials in the food industry include food safety, processing, quality control, packaging, and labeling, enabling functions such as detection of toxins and pathogens, production of biocompatible packaging, enhancement of color, flavor, and aroma, preparation of edible films, and verification of product authenticity without toxicity.

Summary: The concept of nanofluids has shown that the heat transfer potential of working fluids can be improved by dispersing nanosized particles in them. This paper investigates the behavior of solid nanoparticles dispersed in a gaseous medium (nanoaerosol) and analyzes the heat transfer characteristics. The study shows that nanoaerosol-based coolants have the potential to enhance gas-based cooling systems.

Summary: This article presents the moisture harvesting capability of plain finned tube heat exchangers in active atmospheric water generation systems. By reviewing the literature, suitable correlations for predicting water yield in humid air are embedded. Experimental setup and computational simulations are used to analyze the heat exchanger, and the results show that the increase in water yield depends on the number of rows and fin density.

Summary: In this experimental study, convective flow boiling heat transfer using Al2O3/water nanofluid in a horizontal tube was analyzed. The nanofluids exhibited good stability and enhanced thermophysical properties, resulting in a significant increase in heat transfer coefficient, although it also led to an increase in pressure drop. Performance evaluation criteria showed a 94% improvement in overall thermal performance compared to pure water.

Summary: The study evaluates the heat transfer characteristics of water, Al2O3, and Al2O3/Cu nanofluids, analyzing the effects of Reynolds number, volume fraction, and nanoparticle composition on heat transfer properties. Hybrid nanofluids show superior thermophysical properties compared to single particle nanofluids and water, with increasing heat transfer coefficient, Nusselt number, and pressure drop with higher Reynolds number and volume fraction. Overall, 2.0% Al2O3/Cu with equal composition of nanoparticles presented the best heat transfer characteristics among all fluids.
