Kinetic modelling of Biofuels: Pyrolysis and Auto-Ignition of Aldehydes
Chemical Engineering Transactions, 2014 Aldehydes are involved in practically all the oxidation processes of solid and liquid fuels, and they are of concern as pollutants from different combustion systems such as conventional spark-ignition gasoline engines and compression-ignition diesel engines. In the case of biofuel combustion, aldehydes are not only pollutants whose emissions have to be

Auto-ignition Temperature Test Device for Crude Oil in In-situ Combustion
Shiyou jixie, 2017 In order to solve the problem that the ignition temperature is too high to cause the deformation of the pipe string in the process of in-situ combustion, a test device for auto-ignition temperature of crude oil has been developed.

Experimental Study of Ignition over Impact-Driven Supersonic Liquid Fuel Jet
Advances in Mechanical Engineering, 2013 This study experimentally investigates the mechanism of the ignition of the supersonic liquid fuel jet by the visualization. N-Hexadecane having the cetane number of 100 was used as a liquid for the jet in order to enhance the ignition potential of the ...

An iterative dynamic chemical stiffness removal method for reacting flow simulations
Propulsion and EnergyAn iterative dynamic chemical stiffness removal method (IDCSR) based on quasi-steady-state approximation (QSSA) is proposed. The IDCSR method is built on a previously developed non-iterative method which has proved to work well for small timestep sizes ...

Critical Temperature to Auto-Ignition of Leaves
Journal of the Japanese Institute of Landscape Architects, 1984 熱気流による樹木の発火危険を探るため, 発火時の葉温を既往の実験成果から整理するとともに, その検証のための実験を行った。既往の実験姓として空気温度の測定であったため藻内への熱の貯留から発火に至る経過がつかみ得なかった。本実験では藻の麺が発火する時点で近傍の遮敝板内の測点の値を記録することにより, 輻射熱の影響のない適正な葉温 (発火限界温度) を把握することができた。

The two-stage auto-ignition of hydrocarbons and "knock" [PDF]
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1938 Abstract The investigations of Townend and co-workers (1934) have revealed that the spontaneous ignition of higher paraffins in admixture with air consists in certain temperature ranges usually between 270 and 400°C., of a two-stage process, preceded by a time interval t1 prior to the appearance of a cool flame, and a subsequent ...
