Summary: The application of nanofluid in photovoltaic thermal systems is seen as an effective solution for improving output performance. However, there has been limited research on the optimum operating conditions of PVT systems with nanofluid application. This study explores the optimum operating conditions of each PVT output using single-objective optimization and overall performance optimization using multi-objective study. The findings suggest that the collective performance of PVT outputs is optimum at a fluid flow rate of 91 kg/h and a concentration of 0.10%.

Summary: The optimization of extraction conditions for the antioxidant-rich extract from Ficaria Kochii plant was achieved using an ultrasound-assisted system and response surface methodology. The study found that the optimal conditions for extraction using methanol were a solvent-to-raw material ratio of 10%, an extraction time of 50 minutes, and an extraction temperature of 60 degrees C. Under these conditions, the extract had a total phenolic content of 46.379 mg gallic acid equivalents/g dry matter, a total flavonoid content of 11.754 mg quercetin equivalents/g dry matter, and an antioxidant activity of 89.548%. Similarly, the optimal conditions for extraction using water were a solvent-to-raw material ratio of 10%, an extraction time of 30 minutes, and an extraction temperature of 40 degrees C. The resulting extract had a total phenolic content of 51.112 mg gallic acid equivalents/g dry matter, a total flavonoid content of 4.331 mg quercetin equivalents/g dry matter, and an antioxidant activity of 97.004%. This study suggests that the antioxidant-rich extract from Ficaria Kochii could be used as a candidate for food antioxidants and for food storage.

Summary: The present study improves the thermal-hydraulic performance of a circular tube equipped with a delta winglet vortex generator by using a numerical model, investigating two additional parameters, and developing a support vector regression (SVR) for prediction and optimization. The presence of delta winglets disrupts the boundary layer and creates swirling flow, leading to enhanced heat transfer but also increased pressure drop. The addition of SiO2 as a nanofluid further enhances heat transfer. The results of this study provide insights into the best arrangement of delta winglets for a tubular heat exchanger.

Summary: Ammonia is a promising carbon-free fuel and hydrogen carrier. Blending it with hydrogen can address its low flammability issue. However, there is a lack of microscale data on ammonia combustion. This study uses numerical simulations to investigate the stable flame region, NOx emission, and combustion efficiency of ammonia/hydrogen blends in micro-combustors. The findings suggest that a stable flame cannot be achieved at very low or high inlet velocities, and when the hydrogen fraction is below 60% in the fuel. It is recommended to reduce the inlet velocity to improve combustion efficiency when a higher percentage of ammonia is required in the fuel.

Summary: This literature review explores the potentials of liquid micro-/mini-channels in reducing operating temperatures and achieving more uniform temperature distributions in batteries. It includes a classification and overview of battery thermal management methods, introduces different types of lithium-ion batteries and their pros and cons, and describes battery components in detail. The review summarizes studies on the performance of micro-/mini-channels for cooling rectangular and cylindrical batteries, with the key finding being that using a counterflow configuration leads to a relatively uniform temperature distribution and keeps the maximum temperature difference below 5 degrees C. The survey further reveals that proper channel paths and flow configurations can maintain the battery maximum temperature within the safe range of 25 degrees C < T-max < 40 degrees C without significantly affecting the pressure drop.

Summary: This study explores the challenges and opportunities for using renewable energy resources in desalination in the Middle East, where water scarcity is a critical issue. The rapid economic and population growth in the region has increased the demand for freshwater, leading to overexploitation of groundwater resources. Currently, most desalination plants in the Middle East rely on non-renewable energy sources, such as fossil fuels. However, with the expected increase in renewable energy share and the reduction in conventional energy reserves, there is potential for utilizing renewable energy for desalination in the region.

Summary: This study experimentally investigates the impact of metal foam on the thermal and hydrodynamic performance of a parabolic trough collector. Metal foams are known for their high thermal conductivity and thus play a significant role in improving heat transfer. Three different arrangements of metal foams are tested in the absorber tube, and the results show that the periodic array arrangement offers the highest enhancement in thermal efficiency, with a 14% increase. However, this arrangement also significantly increases the friction factor compared to a plain receiver tube.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
