A theory for ignition and deflagration of fuel drops

2nd Annual Meeting, 1965
A theory for ignition and burning of a fuel drop in an oxidizing gas is presented. The model employs a "modified flame surface" denned by use of a "delta function" but retaining effects of finite reaction kinetics. Mass fraction profiles of reactants and products, and temperature profiles are presented; and the mass burning rate as a function of ...

On the ignition of fuel beds by firebrands

Fire and Materials, 2005
AbstractAn experimental apparatus has been built to investigate the ignition of fuel beds as a result of impact with burning firebrands. The apparatus allowed the ignition and deposition of both single and multiple firebrands onto the target fuel bed. The moisture content of the fuel beds used was varied, and the fuels considered were pine needle beds,

Forest fuel ignitibility

Fire Technology, 1970
What is flammability? The author suggests that it consists of ignitibility, sustainability, and combustibility. He defines ignitibility in terms of fuel properties and heat source intensity. Similar methods for determining sustainability and combustibility have not yet been formulated.

Ignition Experiments with Advanced Fusion Fuels

1982
Until recently the realization of a D-3He or a D-D burning reactor had been considered a goal to be achieved in the next century, since a near-term experiment to test the possibility of igniting these kinds of plasmas could not be foreseen.

Piloted ignition of wildland fuels

Fire Safety Journal, 2011
Abstract Piloted ignition of wildland fuel litters was experimentally studied using the FM Global Fire Propagation Apparatus (FPA) with an applied external radiant heat flux up to 30 kW/m2. Fuel types (i.e. Maritime Pine needles and Kermes Oak leaves) and loadings are representative of Mediterranean ecosystems.

Ignition Probability in a Fuel Spray

Japanese Journal of Applied Physics, 1992
Application of the stochastic ignition theory to spontaneous ignition in an n-octane fuel spray injected into high-temperature air behind reflected shock waves in a shock tube is statistically investigated. The total space into which the fuel is injected is optically divided into 25 sections and the induction period of ignition in each section is ...

Ignition of a fuel in contact with an oxidizer

Combustion, Explosion and Shock Waves, 1983
This article considers the problem of the ignition of a semi-infinite volume of condensed fuel placed in contact with an oxidizer having a constant concentration on the contact surface. The oxidizer diffuses into the fuel and enters into a first order exothermal reaction with it.

Additives for Spark Ignition and Compression Ignition engine fuels

Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2017
Fuel additives for automotive applications have been in use for almost as long as the automobile has existed. They provide significant benefits, both in making fuels fit for purpose and to deliver protection and performance benefits. Performance benefits can range from protection against degradation, through recovery of lost performance, all the way to

Ignition Improvers for Ethanol Fuels

SAE Technical Paper Series, 1981
<div class="htmlview paragraph">To facilitate the use of ethanol as a fuel for unmodified conventional diesel engines, ignition-improving additives are needed which in the case described (Brazil) preferably should be based on renewable raw materials, i.e. biomass.
