“…The applicability of mono nanofluids is also limited by a lack of consensus on findings from various researchers, inadequate analysis of suspensions and a lack of standardized procedures for their preparation [210]. It is evident from the literature that one of the major challenges for mono nanofluids is their short-term dispersion stability [211,212], high pumping power and pressure drop [213], reduced thermal performance in turbulent flow [214], high viscosity [215], high cost [216] and limitation to mass production [217][218][219]. However, these challenges must be addressed in future research before conventional nanofluids can be considered for high-heat-flux device cooling application.…”

In recent years, technical advancements in high-heat-flux devices (such as high power density and increased output performance) have led to immense heat dissipation levels that may not be addressed by traditional thermal fluids. High-heat-flux devices generally dissipate heat in a range of 100–1000 W/cm2 and are used in various applications, such as data centers, electric vehicles, microelectronics, X-ray machines, super-computers, avionics, rocket nozzles and laser diodes. Despite several benefits offered by efficient spray-cooling systems, such as uniform cooling, no hotspot formation, low thermal contact resistance and high heat transfer rates, they may not fully address heat dissipation challenges in modern high-heat-flux devices due to the limited cooling capacity of existing thermal fluids (such as water and dielectric fluids). Therefore, in this review, a detailed perspective is presented on fundamental hydrothermal properties, along with the heat and mass transfer characteristics of the next-generation thermal fluid, that is, the hybrid nanofluid. At the end of this review, the spray-cooling potential of the hybrid nanofluid for thermal management of high-heat-flux devices is presented.

Energy is one of the primary foundations supporting evolutionary changes. Heat transfer is improved by increasing the surface area density and/or changing the base fluid characteristics. Because of its small size and improved heat transfer properties, nanofluid cooled microchannel heat sinks (MCHS) have lately become a popular choice for electronics and thermal applications. The influence of employing nanofluids for cooling a chip was investigated experimentally in this work to evaluate the heat transfer characteristics. The investigations were carried out in order to confirm the influence of nanofluid concentration and wall temperature upon thermal-hydraulic properties of the microchannel heat sink. In present study, Al2O3 water nanofluid was employed, with 0.1, 0.2, 0.3, 0.4, and 0.5% nanoparticle volume fractions, mass flow rate (MFL) 2, 5, and 8 m/s at 25, 30 and 35oC inlet tempreture. The resulting experimental findings was verified from results obtained by other researchers, which showed important correlation. The heat transfer efficacy of electronics cooling systems has been enhanced by the nanofluid technology and the configuration of the rectangular heat sink.

“…Nearly 6% of the petroleum products used globally are used in the manufacturing of plastics [ 20 ]. The best method for turning plastic waste into fuel is thermal deterioration, such as pyrolysis [ 21 , 22 ]. The technology of conversion of various plastics into fuel (often termed waste plastic fuel or WPF) is now considered an approach to achieving a circular economy [ 23 , 24 , 25 , 26 , 27 ].…”

“…The technology of conversion of various plastics into fuel (often termed waste plastic fuel or WPF) is now considered an approach to achieving a circular economy [ 23 , 24 , 25 , 26 , 27 ]. The technology of thermal conversion of plastics has been advocated worldwide [ 21 , 28 , 29 , 30 , 31 , 32 ], and research is advancing from the use of clean plastic materials to mixed plastic starting materials [ 26 , 27 , 33 , 34 ], even plastic recovery from landfills [ 22 ]. Nonetheless, the use of blended plastics presents tremendous technological difficulties, e.g., adverse nitrogen substances formed during pyrolysis [ 24 ].…”

The current energy crisis and waste management problems have compelled people to find alternatives to conventional non-renewable fuels and utilize waste to recover energy. Pyrolysis of plastics, which make up a considerable portion of municipal and industrial waste, has emerged as a feasible resolution to both satisfy our energy needs and mitigate the issue of plastic waste. This study was therefore conducted to find a solution for plastic waste management problems, as well as to find an alternative to mitigate the current energy crisis. Pyrolysis of five of the most commonly used plastics, polyethylene terephthalate (PET), high- and low-density polyethylene (HDPE, LDPE), polypropylene (PP), and polystyrene (PS), was executed in a pyrolytic reactor designed utilizing a cylindrical shaped stainless steel container with pressure and temperature gauges and a condenser to cool down the hydrocarbons produced. The liquid products collected were highly flammable and their chemical properties revealed them as fuel alternatives. Among them, the highest yield of fuel conversion (82%) was observed for HDPE followed by PP, PS, LDPE, PS, and PET (61.8%, 58.0%, 50.0%, and 11.0%, respectively). The calorific values of the products, 46.2, 46.2, 45.9, 42.8 and 42.4 MJ/kg for LPDE, PP, HPDE, PS, and PET, respectively, were comparable to those of diesel and gasoline. Spectroscopic and chromatographic analysis proved the presence of alkanes and alkenes with carbon number ranges of C9–C15, C9–C24, C10–C21, C10–C28, and C9–C17 for PP, PET, HDPE, LDPE, and PS, respectively. If implemented, the study will prove to be beneficial and contribute to mitigating the major energy and environmental issues of developing countries, as well as enhance entrepreneurship opportunities by replicating the process at small-scale and industrial levels.
