Summary: Fire accidents, especially oil fires, are unpredictable and often result in serious losses. There are two approaches to studying fire, namely the safety of hazardous substances and the efficiency of fire extinguishing substances. Using a water mist system with 1% polymer composite additives can effectively enhance fire extinguishing efficiency, while 1% NaCl salt additive is negatively correlated with extinguishing efficiency.

Summary: The study investigated the efficacy and requirements of using water mist to extinguish fires in circular, horizontally-oriented ducts under no fire conditions with air flow provided by a blower. Tests showed that the fire could be successfully extinguished regardless of fire size when the water mist concentration exceeded 300 g/m³ in the air flow. The cooling effect of the tested protection was deemed adequate to maintain the structure integrity of exhaust ducts made of various materials during the fire extinguishment process.

Summary: Fire in both vertical and horizontal ducts can be effectively extinguished by discharging water mist upward with the exhaust flow. However, to completely extinguish fire in vertical ducts, water mist should be discharged downward against the exhaust flow. It is important to verify and adjust water mist protections for different duct orientations to ensure applicability.

Summary: In this study, a liquid-phase input end is added to the cup burner to test the fire-extinguishing effect of C6F12O on lithium-ion battery syngas. The minimum extinguishing concentration (MEC) of C6F12O is determined, and the physical and chemical effects of C6F12O on lithium-ion battery syngas fire are quantified using the perfect stirred reactor (PSR) model. The results indicate that the fire-extinguishing effect of C6F12O on lithium-ion battery fire is mainly due to its physical cooling effect.

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.

Summary: Pulsating Heat Pipes (PHP) are passive two-phase heat transfer devices with a simple structure and high heat transfer capabilities. 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. The condenser temperature also affects the initial liquid phase distribution and startup time.
