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.

“…The equipment was placed in the flow path and caused a swirling flow. [ 9 ] Eiamsa‐Ard et al [ 10 ] presented a computational fluid dynamics (CFD) approach for a triple channel with TTI, a twisted channel without an insert, and a simple circular channel. According to the results, the first case had a better thermal performance.…”

“…Sarada et al [ 11 ] investigated the effect of a tube insert to increase the HTR in a horizontal circular tube with air as the fluid and achieved a heat transfer performance 1.8 times better compared with the simple channel. Shelare et al [ 9 ] reported that the use of tube inserts is a very powerful technique to increase heat transfer significantly in laminar flow.…”

Improving the thermal–hydraulic performance of heat exchangers is a critical challenge. In this study, we investigated the impact of twisted tape insert geometrical variables, namely pitch length (P) and diameter (W), on the Nusselt number (Nu) and friction factor (f) within serpentine channels. To accomplish this, we employed computational fluid dynamics (CFD) as our simulation technique, with water as the working fluid. The validity of the CFD data was confirmed, leading to the development of artificial intelligence (AI) subsets: artificial neural network (ANN) and genetic algorithm (GA). In the prediction models, the following input variables were considered: Reynolds number (Re), (P/Dh), and (W/Dh). The ANN and GA models achieved a mean relative error (MRE) of 0.125% and 1.326% for Nu, and 0.139% and 4.104% for f, respectively. These results demonstrate the high accuracy of the correlations, with the ANN model showcasing superior performance.

Renewable energy plays key role in developing any nation. Freshwater is sometimes hard to get to in places that are far aside or poor. Because of this, it is important to have a cheap and effective desalination system that helps these communities grow and helps society as a whole. For example, the development of nanotechnology could help solve water problems by making it easier to get rid of viruses, bacteria, and other contaminants and lowering the cost of purification processes. Desalination is a process that uses a lot of energy and is responsible for most of the costs of running the plant. Also, a lot of the power comes from the greenhouse gas emissions and traditional fossil-fuel-fired power plants which pose a serious danger to ecosystem. In the last few years, many studies have been done on the use of nanotechnology in desalination, the treatment of brine, and the role of renewable energy in desalination. The main goal of this paper is to look at the most important new developments in desalination nanotechnology with respect to energy. Some conclusions and suggestions for future research are made based on the progress made and the problems that still need to be solved.
