Ignition Delay and Unsteady Temperature Effects on Ignition Peak of Solid Rockets [PDF]
38th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2002 The coupled and the uncoupled effects of the ignition delay and the unsteady combustion gas temperature on ignition peak of high velocity transient motors are examined with the help of a two dimensional Navier-Stokes solver. It has been observed through the parametric studies that the altered variation of the ignition delay will alter the transient ...

Shock tube study of JP-10 ignition delay time
, 2007 JP-10 (exo-tetrahydrodicyclopentadiene, C10H16) ignition delay times were measured in a preheated shock tube. The vapor pressures of the JP-10 were measured directly by using a high-precision vacuum gauge, to remedy the difficulty in determining the ...

Ignition delay of bio-fuels in a common-rail compression ignition engine
, 2013 The utility of a novel technique for determining the ignition delay in a compression ignition engine has been shown. This method utilises statistical modelling in the Bayesian paradigm to accurately resolve the start of combustion from a band-pass in ...

Ignition delay in an ethanol fumigated common rail diesel engine
, 2011 A novel method for determining ignition delay is presented. This method utilises combustion resonance as a means of determining the onset of ignition. Results are shown from an ethanol fumigation study comprising of substitutions up to 50% at full, three-

Ignition delay measurements of straight run naphtha
, 2017 Experiments and surrogate modeling have been preformed to assess the ignition characteristics of naphtha for its use in advance engines. Naphtha, which has low octane number, is proposed as a promising fuel for advanced compression ignition (CI) engines.

Shock Tube Ignition Delay Data Affected by Localized Ignition Phenomena
, 2017 Shock tubes have conventionally been used for measuring high-temperature ignition delay times ~ O(1 ms). In the last decade or so, the operating regime of shock tubes has been extended to lower temperatures by accessing longer observation times.
