Ignition delay in multifuel mixtures
Combustion, Explosion, and Shock Waves, 2007Methods used to calculate the ignition delay (induction time) of combustible systems consisting of several individual fuels are discussed. A modification of the Arrhenius equation for multifuel mixtures is proposed, which improves the agreement between numerical and experimental data. The method proposed is analyzed by an example of two-fuel systems on

Transactions of the American Institute of Electrical Engineers, 1951
IMPROPER PERFORMANCE of gun-type oil burners operating with from 5 to 15 gallons of oil per hour led to an investigation that pointed to ignition delay as the cause of malfunctioning. The delay referred to is the time interval occurring between application of voltage to the ignition transformer primary and the initiation of the spark discharge in the ...

Ignition delay characteristics of methane fuels
Progress in Energy and Combustion Science, 1994Abstract A comprehensive literature search and a series of shock-tube experiments were undertaken to determine the ignition delay times for mixtures of methane with ethane, propane or butane, and for a typical natural gas fuel. Ignition delay experiments were conducted at equivalence ratios of 0.45–1.25 for temperatures 1300–2000 K and pressures 3–15

Ignition delay of composite solid propellants
Combustion and Flame, 1977Abstract Ignition delay of phenol-formaldehyde composite propellants was measured by a hot plate technique. The activation energy for the preignition reactions has been computed using the Arrhenius type expression for ignition delay.

Ignition Delay for Atmospheric Pressure Microplasmas
Contributions to Plasma Physics, 2009AbstractThe ignition process in microplasmas is characterized by time resolved microwave reflection coefficient measurements, using a specially equipped vector network analyzer. We measured the time between the switching on of the microwave power and the onset of the plasma state in air at atmospheric pressures. The delay time decreases from approx.

Ignition-delay times in laser initiated combustion
Applied Optics, 1981A single pulse from a TEA CO(2) laser is used to heat 1:7:14 mixtures of SF(6):CH(4):O(2) to temperatures near 1000 K. A short- or long-duration pulse (one-half the energy deposited in 0.25 or 0.82 microsec, respectively) from a second TEA CO(2) laser is used to ignite the mixture. At comparable values of absorbed energy from the second laser, ignition-

Experimental Investigation on the Ignition Delay Time of Plasma-Assisted Ignition
International Journal of Turbo & Jet-Engines, 2016AbstractThis paper investigates the ignition performances of plasma-assisted ignition in propane/air mixture. The results show that a shorter ignition delay time is obtained for the plasma ignition than the spark ignition and the average ignition delay time of plasma-assisted ignition can be reduced at least by 50%.
