Combustion Characteristics and NO Formation Characteristics Modeling in a Compression Ignition Engine Fuelled with Diesel Fuel and Biofuel

Journal of Combustion, Volume 2021, Issue 1, 2021., 2021
Compression ignition engine modeling draws great attention due to its high efficiency. However, it is still very difficult to model compression ignition engine due to its complex combustion phenomena. In this work, we perform a theoretical study of steam injection being applied into a single‐cylinder four‐strokes direct‐injection and naturally ...

Effect of combustion pressure on regression rate of solid fuel under an impinging oxidizer jet counterflow diffusion flame

Journal of Thermal Science and Technology, 2014
Flame spread and counterflow diffusion flame experiments are widely conducted to investigate the combustibility of solid fuels. Although the use of the gas phase Damköhler number to organize the flame spread rate or regression rate of a solid fuel is ...

Oxygen combustion of CH4-CO2 mixture in a small-scale counterflow burner

Journal of Thermal Science and Technology, 2018
Oxygen combustion of CH4-CO2 mixture in a small-scale counterflow burner was studied. A diffusion flame was stabilized in the gap between opposed ports ejecting fuel and oxygen gases, and its thickness which depended on the gap distance between burner ...

Influences of stretch and curvature on the temperature of stretched cylindrical diffusion flames

Journal of Thermal Science and Technology, 2016
The structure of a counterflow-type cylindrical diffusion flame was studied experimentally to determine the effect of stretch and curvature. The cylindrical flame used in this study had a concave curvature with respect to the fuel stream.

Flame sheet starting estimates for counterflow diffusion flame problems

Journal of Computational Physics, 1987
The authors develop a flame sheet starting procedure for the numerical modelling of laminar counterflow diffusion flame problems. The model couples the equations of mass and tangential momentum with a Shvab- Zeldovich equation to provide estimates for the mass flux in the transverse direction, the similarity function, the temperature and the stable ...

Combustion Reactions in Silane–Air Flames II. Counterflow Diffusion Flame [PDF]

Bulletin of the Chemical Society of Japan, 1991
Abstract A detailed chemical reaction scheme and a full set of governing equations for fluid dynamics were used to elucidate the chemical and physical phenomena involved in a silane–air counterflow diffusion flame, where the fuel and air issue from the lower and upper nozzles, respectively.

Extinction behavior of addition of PMMA powder into counterflow diffusion flame of methane and nitrogen and high temperature air

Nihon Kikai Gakkai ronbunshu, 2020
A counter-flow diffusion flame formed of a fuel consisting of methane and nitrogen, and a oxidizer of air heated to 500℃ was applied to clarify the influence on the extinction limit when fine powder of polymethyl methacrylate (PMMA) was added to the fuel.

Insight Into Puncture‐Induced Thermal Runaway in Lithium‐Ion Batteries to Reduce Fire Risks in Electric Vehicle Collisions

Battery Energy, Volume 4, Issue 6, November 2025.
This review examines nail penetration‐induced thermal runaway (TR) in lithium‐ion batteries, analyzing experimental and modeling studies on critical factors—battery materials, nail properties, state of charge, and penetration dynamics. It also explores internal short‐circuit modes, TR severity, and safety solutions such as advanced separators, non ...

Ab Initio Study of the Gas‐ and Liquid‐Phase Hydrogen Abstraction From Dimethyl‐, Diethyl‐, and Ethyl–Methyl Carbonates by Ḣ${\dot{\mathrm{H}}} $ and Ċ${\dot{\mathrm{C}}} $ H3 and Subsequent Reactions

International Journal of Chemical Kinetics, Volume 57, Issue 11, Page 652-661, November 2025.
ABSTRACT Dimethyl‐, diethyl, and ethyl–methyl carbonate are important components of lithium batteries. They are used as solvents and comprise the medium through which the lithium ions move between the anode and the cathode during charge and discharge. However, these species are susceptible to decomposition if thermal runaway occurs, forming flammable ...
