CFD simulations of Hybrid and Composite Nanomaterials for Enhanced Heat Transfer in Heat Exchangers

This quantitative research explores features of impact of nanomaterials, hybridized nanomaterials, and composite nanomaterials on heat exchangers. Heat exchangers are used widely in various industrial processes and are considered important elements since they extend the lifespan of equipment through proper management of thermal loads. It has been evident that incorporation of TiO2 nanomaterials will improve progressively the thermal conductivity of heat exchange equipment and, thus, the overall efficiency of heat exchangers. In the present research, the findings have been derived through the use of computational fluid dynamics (CFD) analysis for studying heat exchange characteristics and the flow of fluids in heat exchangers incorporating various forms of nanomaterials. The study considered the influence of adding Al2O3 with CuO hybridized nanomaterials onto the heat exchanger as its material. The temperature got low at 43.3 °C, which showed the performance of the nanomaterials, and reduced further afterwards to 41.93 °C within just 10 minutes. The inclusion of the nanohybrid in combination approached the premium down to 36.6°C twelve minutes later. The result indicates that the use of the nanocomposite is well justified for improving the quality of the cooling process. Contour temperatures, velocities, and pressure show heat transfers and quantities of fluid density when hybrid nanomaterials are mixed with multiple substances. It was at 313.5 K that the maximum temperature was at, and the velocity arrived at 0.45 m/s, which subsequently decreased to 0.33 m/s. The increase in pressure was at 1035 pa. This translates to the difference in density of the absorbent fabric and the nanomaterials.
