Summary: The recently invented grasshopper optimization algorithm (GOA) was used to optimize the performance and emissions of a diesel engine running on a ternary fuel blend. Regression modeling was used to calculate the mathematical equations between the factors (ethanol ratio, biodiesel ratio, engine load) and the responses (BSFC, BTE, HC, CO2, NOx, CO). The results showed that the grasshopper optimization algorithm successfully maximized BTE and minimized the other responses, indicating its potential for improving engine performance and emissions.

Summary: In recent years, the search for new clean fuels to replace fossil diesel has become crucial due to the shortage of fossil oil resources and environmental pollution problems. Biodiesel has gained attention for its environmental friendliness, renewable features, and wide range of sources. However, the use of biodiesel often leads to higher NOx emissions. Water, as a fuel additive, can lower the combustion temperature and reduce NOx emissions but also brings new challenges like increased CO and HC emissions. Nanoparticles are expected to address these issues with their higher surface area-to-volume ratio and catalytic properties. Therefore, it is important to investigate the effects of nanoparticles and water on the performance of biodiesel and its blends with diesel.

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.

Summary: This paper investigates the heat transfer mechanism and factors influencing thermal radiation in the process of supercritical water gasification (SCWG) of coal, and proposes a comprehensive numerical model to simulate the process. 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.

The actual unpredictability of their dynamic behavior during startup and thermal crisis hinders their large-scale application. An experimental apparatus is designed to investigate these phenomena systematically. The results show that increasing the number of evaporator sections and condenser temperature improves the performance of PHP.
