A study of the turbulent jet flow field in a methane fueled turbulent jet ignition (TJI) system

Combustion and Flame, 2017
Abstract This paper analytically and computationally examines the transient jet used to ignite combustible mixtures during Turbulent Jet Ignition (TJI). In TJI the ignition source, which originates in the prechamber, enters through a connecting nozzle into the main chamber as a transient high temperature jet of reacted mixture, reacting mixture and ...

Effect of Turbulence on Forced Ignition of Jet-A/Air Mixtures

Journal of Engineering for Gas Turbines and Power, 2022
AbstractConsistent ignition of reactive mixtures in turbulent conditions continues to be a challenge, particularly for large, multicomponent fuels. Prior work has shown that turbulence can affect ignition parameters such as flame speed, mixture temperature, and minimum ignition energy (MIE).

Thermal efficiency of a dual-mode turbulent jet ignition engine under lean and near-stoichiometric operation

open access: yesInternational Journal of Engine Research, 2017
Turbulent jet ignition is a combustion technology that can offer higher thermal efficiency compared to the homogeneous spark ignition engines. A potential combustion-related challenge with turbulent jet ignition is the pre-chamber misfiring due to ...

Spark ignition of lifted turbulent jet flames

Combustion and Flame, 2006
This paper presents experiments on ignition and subsequent edge flame propagation in turbulent nonpremixed methane jets in air. The spark position, energy, duration, electrode diameter and gap, and the jet velocity and air premixing of the fuel stream are examined to study their effects on the ignition probability defined as successful flame ...
