Ignition Delay Time and Laminar Flame Velocity for a Combined Laser–Microwave Ignition
IEEE Transactions on Plasma Science, 2011An analysis of the ignition delay time dependence on microwave energy input time, electric field strength, and discharge energy at high-pressure conditions is presented for a combined laser-microwave ignition. The existence of a saturation power effect at high-pressure conditions is predicted.

Numerical simulation of ignition mode and ignition delay time of pulverized biomass particles
Combustion and Flame, 2019Abstract In this paper, numerical simulations were carried out to identify the mode of ignition and ignition delay time of pulverized biomass particles in hot flue gas produced by a methane/air flame. In the experiments, it was observed that for most biomass residues the dominant combustion mode was the staged gas-phase ignition in the surrounding ...

Ignition delay time in swirling supersonic flow
Acta Astronautica, 2013Abstract Supersonic hydrogen–air cylindrical mixing layer is numerically analyzed to investigate the effect of inlet swirl on ignition delay time in scramjets. Combustion is treated using detailed chemical kinetics. One-equation turbulence model of Spalart and Allmaras is chosen to study the problem and advection upstream splitting method is used as ...

Piloted ignition delay times on optically thin PMMA cylinders
Proceedings of the Combustion Institute, 2019Abstract The theory to predict ignition of solid fuels exposed to incident radiant heat fluxes has permitted to obtain simple correlations of the ignition delay time with the incident heat flux which are useful in practical engineering applications.

Factors influencing ignition delay time of composite solid propellants
8th Aerospace Sciences Meeting, 1970Abstract : Thermal events occurring on an near a propellant surface during ignition were observed simultaneously using an optical detector operating over two narrow wavelengths: 3.79 micrometers which is free of interfering CO2 and H2O thus representing radiation from the surface and 0.43 micrometers which detects the CH radical in the flame above the ...

Prediction of Ignition Delay Time Using Artificial Neural Network
2023Fuel combustion is a highly complicated process and is affected by many physical and chemical factors, which also made the prediction and measurement of ignition delay time a complicated, slow, and not cost-effective process. Ignition delay time in engine combustion is considered to be one of the most important global control properties.

Shock tube measurements of branched alkane ignition delay times
Fuel, 2014Abstract Ignition delay times for three branched alkanes: 2,4-dimethylpentane, 2,5-dimethylhexane and iso-octane, were measured behind reflected shock waves. The ignition delay time measurements cover the temperature range of 1313–1554 K, with pressures near 1.5 and 3 atm, equivalence ratios of 0.5 and 1 in 4% oxygen/argon. Regression analyses of the

High temperature ignition delay times of C5 primary alcohols
Combustion and Flame, 2013Abstract Ignition delay times of the three C5 primary alcohol isomers (n-pentanol, iso-pentanol and 2-methyl-1-butanol) were measured behind reflected shock waves. Experiments were conducted in the temperature range of 1100–1500 K, pressures of 1.0 and 2.6 atm, equivalence ratios of 0.25, 0.5 and 1.0, and O2 concentration in the fuel/O2/Ar mixtures ...
