“…Moreover, the pressure is dropped across the heat sink as the Reynold’s number increases, which enhances the shear stresses and skin friction with the metal foam and finned heat sink. These results were observed to be in good agreement with those in [ 39 ]. As shown in Figure 25 , the backflow observed in previous cases is eliminated when the volume flow rate reaches 0.525 LPM.…”

Microelectronic components are used in a variety of applications that range from processing units to smart devices. These components are prone to malfunctions at high temperatures exceeding 373 K in the form of heat dissipation. To resolve this issue, in microelectronic components, a cooling system is required. This issue can be better dealt with by using a combination of metal foam, heat sinks, and nanofluids. This study investigates the effect of using a rectangular-finned heat sink integrated with metal foam between the fins, and different water-based nanofluids as the working fluid for cooling purposes. A 3D numerical model of the metal foam with a BCC-unit cell structure is used. Various parameters are analyzed: temperature, pressure drop, overall heat transfer coefficient, Nusselt number, and flow rate. Fluid flows through the metal foam in a turbulent flow with a Reynold’s number ranging from 2100 to 6500. The optimum fin height, thickness, spacing, and base thickness for the heat sink are analyzed, and for the metal foam, the material, porosity, and pore density are investigated. In addition, the volume fraction, nanoparticle material, and flow rate for the nanofluid is obtained. The results showed that the use of metal foam enhanced the thermal performance of the heat sink, and nanofluids provided better thermal management than pure water. For both cases, a higher Nusselt number, overall heat transfer coefficient, and better temperature reduction is achieved. CuO nanofluid and high-porosity low-pore-density metal foam provided the optimum results, namely a base temperature of 314 K, compared to 341 K, with a pressure drop of 130 Pa. A trade-off was achieved between the temperature reduction and pumping power, as higher concentrations of nanofluid provided better thermal management and resulted in a large pressure drop.

In this study, new polyurethane composites have been prepared by the treatment and functionalized of waste leave sidr powder with polymeric methylene diphenylene diisocyanate (PMDI), and the mixing effect on the properties of these composites were evaluated using different weight percentages of carbon fibers (CFs). Thermal treatment of the prepared natural composites was done at different temperatures, where the studies used the XRD and SEM showed the heat treatment at 900 °C, lead to formation of Nanocomposites. On the other hand, the flammability test of these composites and hybrid composites (containing different % of CF) were a analysed using UL-94V methods, the results show, that these prepared composites were flammable and fire resistant. Also, the effect of CF on the ablation properties of these composites was evaluated using an oxygen-acetylene ablation device, and along with the increasing the content of CFs, the mass and linear ablation rates both decreases, while the insulations index were increased.

The carbon fibers have been employed to form the high performance composites. The use and compatibility of carbon fibers have gained research interest. Incidentally, the nanocarbon nanostructures such as carbon nanotube, graphene, nanodiamond, and fullerene have been deposited on the carbon fiber surface to increase the interfacial linking with the matrices. Various physical and chemical methods have been used to deposit the nanocarbon on the carbon fiber surface including the chemical vapor deposition, electrospraying, electrophoretic deposition, etc. This review basically highpoints the prospective of the formation of the polymer/fiber composite and polymer/fiber/nanofiller nanocomposite for the advanced structures. The effect of the addition of the nanocarbon on the properties of the polymer/carbon fiber materials have been observed. Specifically, the morphology, strength, toughness, storage modulus, thermal stability, and other physical characteristics have been observed. Moreover, the interfacial adhesion and resulting interfacial features of the polymer/fiber/nanofiller nanocomposite have also been perceived.
