    Abstract Lithium-ion batteries (LiBs) have superior energy density and lifetime compared to battery technologies such as lead acid. Despite the widespread application of LiBs in energy storage systems, electronic devices, aerospace and the automotive industry, they present a fire risk. In this study, experiments were conducted to characterize the thermal behavior of the electrolyte (as the main contributor to LiB fires) using a cone calorimeter; investigate the interactions of water mist and a Bunsen burner, as a precursor to examining the effectiveness of a water mist suppression system in extinguishing a LiB fire. In the present work, we have endeavored to… More >

    Abstract To thoroughly study the extinguishing effect of a high-pressure water mist fire extinguishing system when a transformer fire occurs, a 3D experimental model of a transformer is established in this work by employing Fire Dynamics Simulator (FDS) software. More specifically, by setting different parameters, the process of the high-pressure water mist fire extinguishing system with the presence of both diverse ambient temperatures and water mist sprinkler laying conditions is simulated. In addition, the fire extinguishing effect of the employed high-pressure water mist system with the implementation of different strategies is systematically analyzed. The extracted results show that a fire source… More > Graphic Abstract

    A Numerical Study on the Extinguishing Performances of High-Pressure Water Mist on Power-Transformer Fires for Different Flow Rates and Particle Velocities

    Yongheng Ku1, Jinguang Zhang2,3, Zhenyu Wang3,4, Youxin Li3,5, Haowei Yao3,5,*

    FDMP-Fluid Dynamics & Materials Processing, Vol.17, No.6, pp. 1077-1090, 2021, DOI:10.32604/fdmp.2021.015779

    Abstract In order to study the extinguishing performance of high-pressure-water-mist-based systems on the fires originating from power transformers the PyroSim software is used. Different particle velocities and flow rates are considered. The evolution laws of temperature around transformer, flue gas concentration and upper layer temperature of flue gas are analyzed under different boundary conditions. It is shown that the higher the particle velocity is, the lower the smoke concentration is, the better the cooling effect on the upper layer temperature of flue gas layer is, the larger the flow rate is and the better the cooling effect is.

    Analysis of the Thermal Behavior of a Lithium Cell Undergoing Thermal Runaway

    Qifei Du1, Zhigang Fang2,3,*

    FDMP-Fluid Dynamics & Materials Processing, Vol.17, No.5, pp. 887-898, 2021, DOI:10.32604/fdmp.2021.016265

    Abstract This study examines the thermal runaway of a lithium ion battery caused by poor heat dissipation performances. The heat transfer process is analyzed on the basis of standard theoretical concepts. Water mist additives are considered as a tool to suppress the thermal runaway process. The ensuing behaviour of the battery in terms of surface temperature and heat generation is analyzed for different charge and discharge rates. It is found that when the remaining charge is 100%, the heat generation rate of the battery is the lowest, and the surface temperature with a 2C charge rate is higher than that obtained… More >

    Suppression Capability Investigation for a Water Mist System in a Basement Building Fire

    S.C. Wang1, C.S. Lin2

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.7, No.4, pp. 189-196, 2008, DOI:10.3970/icces.2008.007.189

    Abstract Protecting against basement fires in commercial buildings is of major concern in Taiwan. Basements typically fill with high-temperature dense smoke rapidly during a fire, frequently generating deadly conditions that hinder escape from a fire. The water-mist fire suppression system (WMFSS) is a highly efficient fire suppression device that enhances the safety of people during a basement fire. The tiny water droplets with various diameters can absorb large amount of heat and the water vapors can prevent the occurrence of flashover during a building fire. This study investigates fire-suppression characteristics using a WMFSS in a basement barbershop fire accident in Taiwan.… More >
