Auto-ignition of a polydisperse fuel spray

Proceedings of the Combustion Institute, 2007
Abstract In the present paper, the effect of fuel spray polydispersity on the auto-ignition process in a fuel cloud is considered. In many engineering applications it is common practice to relate to the actual polydisperse spray as being equivalent to a monodisperse spray with all droplets therein having some average diameter.

Auto-ignition of hydrazine by engineering materials

16th Aerospace Sciences Meeting, 1978
Hydrazine, being a monopropellant, can explode and/or detonate in contact with some materials. This has been generally recognized and minimized by testing the compatibility of engineering materials with hydrazine at ambient temperature. Very limited tests have been done at elevated temperatures.

Modelling auto-ignition in a turbulent medium

Symposium (International) on Combustion, 1992
The problem of auto-ignition in an initially non-premixed, homogeneous, isotropic turbulent medium is considered. The equations governing the combined processes of mixing and chemical reaction are formulated. Mixing and reaction progress are described by a mixture-fraction variable ξ and a reaction-progress variable c, respectively.

Production-feasible controlled auto-ignition

ATZautotechnology, 2007
Controlled Auto-Ignition (CAI) is a unique form of petrol combustion. To date, most work has been based on a research environment that requires complex hardware in order to function. Mahle Powertrain has focused its work on achieving a near-term, low-cost, production-feasible controlled auto ignition solution.

An Experimental Approach to the Controlled Auto-Ignition

SAE Technical Paper Series, 2007
<div class="htmlview paragraph">Auto-ignition may be considered as the ultimate combustion process for vehicle engines. Regarding combustion control, ignition timing and heat release are the chief concerns. The former is finding a solution, however the latter has, as yet, several approaches.</div> <div class="htmlview paragraph">As a ...

External heating of electrical cables and auto-ignition investigation

Journal of Hazardous Materials, 2017
Electric cables are now extensively used for both residential and industrial applications. During more than twenty years, multi-scale approaches have been developed to study fire behavior of such cables that represents a serious challenge. Cables are rather complicated materials because they consist of an insulated part and jacket of polymeric ...

Theory of ignition and auto-ignition

Combustion and Flame, 1962
Abstract A fuel-oxidant system may auto-ignite, be ignited by a source, or remain non-inflammable depending upon the ambient temperature, pressure, composition, geometry of the container, etc. This paper presents a theoretical attempt to explain how all these observed phenomena can occur in a given chemical system.

Modeling and Simulation of Gasoline Auto-Ignition Engines

IFAC Proceedings Volumes, 2009
Abstract Both the customer demand for increasing mobility and the emission legislation lead to a challenge for engine researchers and developers in order to reduce emissions and fuel consumption. One approach that is presently under extensive investigation is to implement auto-ignition combustion in gasoline engines.

Auto-ignition synthesis of nanocrystalline BaTi4O9 powder

Journal of Materials Chemistry, 2001
Monophasic BaTi4O9 powder has been prepared by an auto-ignition route. The auto-ignition of the gel, prepared by thermal dehydration of a pH adjusted citrate–nitrate solution, directly resulted in voluminous BaTi4O9 powder with traces of carbonaceous material.

The Auto-Ignition of Multicomponent Fiber Systems

1973
Using a simple experimental procedure for determining the time until ignition after a material is plunged into a heated air environment, it is possible to obtain kinetic data for this auto-ignition process. Results on homogeneous polymeric materials show that, while the rate controlling factors in every case are physical rather than chemical, ignition ...
