Spark Ignition of Turbulent Methane/air Mixtures Revealed by Time-resolved Planar Laser-induced Fluorescence and Direct Numerical Simulations
نویسندگان
چکیده
By use of high-speed planar laser-induced fluorescence (PLIF) imaging, the evolution of turbulent reactive flows was recorded and studied in real time in a filmlike manner. The technique was used to track the concentration field of the OH radical, which was produced during spark ignition of a turbulent methane/air mixture. The results were compared qualitatively to a two-dimensional direct numerical simulation of the same system using a detailed chemical mechanism and a detailed transport model.

Characterisation of a spark ignition system by planar laser-induced fluorescence of OH at high repetition rates and comparison with chemical kinetic calculations
This study reports the application of a novel, high speed laser-detector system for the time-resolved study of flame propagation in a well-controlled spark ignition system. The ignition system allowed full and reproducible control over the energy deposited during breakdown and the ensuing arc discharge of the spark plasma. Ignition was performed in a closed vessel which was filled with stoichio...

This paper reports on the development of novel time resolved spectroscopic imaging techniques for the study of spark ignition phenomena in combustion cells and an SIengine. The techniques are based on planar laser induced fluorescence imaging (PLIF) of OH radicals, on fuel tracer PLIF, and on chemiluminescence. The techniques could be achieved at repetition rates reaching several hundreds of ki...
متن کاملNumerical Investigation of Spark-ignition in a Laminar Methane-air Counterflow
Simulations of forced ignition in a non-premixed laminar counterflow are used to study the effect of the strain rate on ignition success. A one dimensional calculation is performed, using detailed methane chemical kinetics, and treating the ignition event as an instantaneous heat release. Ignition success is seen to depend on the mixture composition and spark location, resulting in lean and ric...

Large Eddy Simulation (LES) is used to compute the spark ignition in a turbulent methane jet flowing into air. Full ignition sequences are calculated for a series of ignition locations using a one-step chemical scheme for methane combustion coupled with the thickened flame model. The spark ignition is modeled in the LES as an energy deposition term added to the energy equation. Flame kernel for...

High speed planar laser induced fluorescence (PLIF) imaging of the OH radical is presented in a turbulent nonpremixed methane-air flame. Sequences of up to eight successive PLIF images could be resolved sequentially at several kHz repetition rates. Turbulent flow phenomena such as vortex formation and air entrainment in the flow could be visualised and their development tracked in real time. Tu...
