Low-Temperature Hypergolic Ignition of 1-Octene with Low Ignition Delay Time

The Journal of Physical Chemistry A, 2020
The attainment of the efficient ignition of traditional liquid hydrocarbons of scramjet combustors at low flight Mach numbers is a challenging task. In this study, a novel chemical strategy to improve the reliable ignition and efficient combustion of hydrocarbon fuels was proposed.

An approach of droplet ignition delay time

Heat Transfer—Asian Research, 2008
AbstractWhen a droplet is suddenly injected into a high‐temperature environment, the droplet self‐ignition phenomenon occurs. A simple model, based on the temperature history of target gas mixture of which the equivalent ratio is equal to 1, was proposed to predict the droplet ignition delay time in this paper. This approach clearly divides the droplet

Experimental Investigation on the Ignition Delay Time of Plasma-Assisted Ignition

International Journal of Turbo & Jet-Engines, 2016
AbstractThis 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%.

Ignition Delay Times of Jet-A/Air Mixtures

50th AIAA Aerospace Sciences Meeting including the New Horizons Forum and Aerospace Exposition, 2012
Ignition of Jet-A/air mixtures was studied behind reflected shock waves. Heating of shock tube at temperature of 150 0 C was used to prepare a homogeneous fuel mixture. Ignition delay times were measured from OH emission at 309 nm (A 2 Σ – X 2 Π) and from absorption of He-Ne laser radiation at 3.3922 µm.

Ignition-delay times in laser initiated combustion

Applied Optics, 1981
A 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-
