Summary: Liquid coolant is commonly used to lower the temperature of an object. By introducing metal nanoparticles into a base fluid such as water, the heat transfer performance of the coolant can be increased. Hybrid nanofluids, which mix two types of metal nanoparticles with high thermal conductivity, have been developed to further enhance the heat transfer performance. In this study, a numerical analysis was conducted to investigate the effects of different types of coolants on heat transfer performance. The results showed that hybrid nanofluids had the highest heat transfer performance compared to pure water and single particle nanofluids. A mathematical formulation was also developed to describe the correlation between Reynolds number and volume concentration on the average heat transfer coefficient.

Summary: An experimental study was conducted to investigate the heat transfer and flow characteristics of a heavy vehicle radiator using nanofluid. Deionized water mixed with anatase TiO2 nanoparticles was used as the nanofluid. Experiments were performed with different volume concentrations of TiO2 nanoparticles, inlet temperatures, and volume flow rates. The results showed that the highest heat transfer rate, heat transfer coefficient, and Nusselt number were observed at a volume concentration of 0.05%, an inlet temperature of 80 ?, and a volume flow rate of 11 LPM. The maximum enhancement in heat transfer rate, heat transfer coefficient, and Nusselt number compared to pure water were 22.2%, 48.2%, and 48.1% respectively. The performance coefficient was found to be above unity in the volume concentration range of 0.025-0.05% for each inlet temperature and flow rate.

Summary: The study investigates the thermal performance of a helical tube three-fluid heat exchanger using graphene/water nanofluids, showing an increase in overall heat transfer coefficient with higher fluid flow rates and variation in effectiveness due to different fluid flow speeds. Comparison with a double-pipe helical tube heat exchanger reveals significant differences in Nusselt numbers and correlations. Semiempirical correlations proposed for the triple-fluid helical tube heat exchanger align well with experimental results and are useful for multiple fluid flows and thermal communications in heat exchangers.

Summary: The combustion of fuel in an engine generates a large amount of heat, which needs to be dissipated to prevent engine overheating. Liquid cooling systems with radiators are commonly used for this purpose. Nanofluids, with their higher thermal conductivity, have shown potential as better alternatives to traditional coolants such as water and ethylene glycol. In this study, the thermal performance of water and aluminum oxide nanofluids in a crossflow radiator was investigated numerically, and the results demonstrated that nanofluids outperformed water in terms of heat transfer rate and coefficient.

Summary: In order to design an economically efficient absorption process with minimal energy consumption, the solubility of gas in the desired solvent needs to be measured and its non-ideality at different operating conditions needs to be evaluated. Thermodynamic modeling is used to predict solubility so that it can be confidently used over a wide range of temperature and pressure. In this study, the solubility of pure ethane gas in N-methyl-2-pyrrolidone (NMP) solvent was investigated at different temperatures and pressures, and the kinetic and equilibrium data of absorption were calculated. Different thermodynamic models were applied to adjust the binary interaction parameters and predict solubility, with good agreement observed.

Summary: The diffusion coefficient of carbon dioxide in light oil was measured using the pressure decay method at different temperatures and pressures. The molecular diffusion mechanism of gas in liquid was studied and a mathematical model based on Fick's second law was developed. The numerical values of the diffusion coefficient were found to be greater than expected, indicating the presence of a stronger mass transfer mechanism such as natural convection. The effect of temperature on the diffusion coefficient was opposite to the expected behavior, suggesting the influence of other factors.

Summary: Several experiments have been conducted to study the impact of operational parameters on calcium carbonate fouling under single phase forced convection and two-phase subcooled flow boiling. The presence of suspended particles in the solution led to the formation of both particulate and crystallization fouling. Contrary to previous findings, no induction period was observed in this study, and the fouling curves showed an asymptotic trend similar to particulate fouling. Bubbles were found to mitigate fouling formation, contrary to other studies which considered bubble formation as the cause of fouling intensification. Additionally, increasing heat flux was observed to decrease deposition due to the formation of more easily removed aragonite polymorphs at high heat fluxes.

Summary: Petrochemical companies, especially those with olefin plants, have a significant negative impact on air quality, the environment, and human health. The measurement of emission rates and dispersion of pollutants is necessary to establish policies and restrictions on their release. In this study, the concentrations of dangerous pollutants such as CO, NOx, and SO2 were measured from seven active stacks of an olefin plant in Iran throughout the year. Dispersion modeling and meteorological data were used to predict the concentration of pollutants in residential areas surrounding the plant. The results showed that NOx emissions were the highest, exceeding the emission rates of CO and SO2 in all seasons. The dispersion patterns indicated that the pollutants moved towards the southwest, away from residential areas, due to prevailing wind directions. However, the concentrations of CO, SO2, and NOx exceeded the World Health Organization's air quality guidelines in Sarbandar, particularly in summer, fall, and winter, due to the proximity of residential areas to the emission sources.

Summary: In the past decade, there has been a growing interest in studying energy systems for the combined management of power vectors. Most of the published works focus on finding the optimal design and operations of Multi Energy Systems (MES). However, for newcomers to this field, understanding how to achieve the desired optimization details while controlling computational expenses can be challenging and time-consuming. This paper presents a novel approach to analyzing the existing literature on MES, with the aim of guiding practical development of MES optimization. Through the discussion of six case studies, the authors provide a mathematical formulation as a reference for building the model and emphasize the impact of different aspects on the problem nature and solver selection. In addition, the paper also discusses the different approaches used in the literature for incorporating thermal networks and storage in the optimization of multi-energy systems.

Experimental validation results show that thermal radiation accounts for a significant proportion of the total heat exchange in the reactor and a large amount of radiant energy exists in the important spectral range of supercritical water. Enhancing radiative heat transfer can effectively increase the temperature of the reaction medium and the gasification rate.
