Abstract:

Examination of the available ignition delay time data and correlations in the case of methane, butane, heptane, decane, kerosene, Jet-A and ethylene fuels, allowed the derivation and recommendation of standard equations for this property. In this study, a new accurate substance dependent equation for ignition delay time as a function of pressure, number of carbon atoms, mixture equivalence ratio, fuel mole fraction and temperature has been developed to estimate ignition delay time of some hydrocarbon fuels. With the presented model, ignition delay time has been calculated and compared with the data reported in literature. The accuracy of the obtained model has been compared to the mostly used predictive models and the comparison indicated that the proposed correlation provides more accurate results than other models used in the previous works.

Oxidation and Ignition Characteristics of Hydrocarbon Fuels

A research program studying the oxidation and ignition characteristics of hydrocarbon fuels has been conducted. The program was initiated in October 1985 with the awarding of a research grant through the Army Research Office (Grant No. DAAG 29-85-K-0253, Project No. 22437-EG) and ran through November 1989. The research program entailed mechanistic studies examining the oxidation chemistry of si...

Specific Impulse and Ignition Delay Time Assessment for DMAZ with Liquid Oxidizers for an Upper Stage Rocket Engine

2-Dimethyl amino ethyl azide (DMAZ) has attracted much attention as a suitable liquid fuel replacement for monomethyl hydrazine (MMH) and unsymmetrical dimethyl hydrazine (UDMH) in propellant systems because, in contrast to these fuels, it is noncarcinogen. In this research, performance, and ignition delay time of DMAZ were studied with common liquid oxidizers such as inhibited red fuming n...

Correlation of Ignition Delay for Various Methane Based Fuel Blends

It is very well known that the efficiency of an SI engine is limited by knock occurrence. As a compromise between knocking combustion avoidance and an accepted level of efficiency, an engine is typically operated at very close to the knocking boundary. However, the position of an engine knocking boundary is shifted if the fuel composition changes. The description of this abnormal combustion is ...

Mechanism Generation for Hydrocarbon Fuels

ion The linear alkanes, as most simple components, provide the fundamentals of fuel modeling in the case of more complicated components (alkenes, aromatics, polycyclic aromatic hydrocarbons, etc.). Meanwhile n-alkanes or blending of n-alkanes are by far the best studied class of compounds for which reliable, detailed chemical kinetic models for combustion exist and supposed to be the suitable s...

Alternative Fuels for Spark Ignition Engines

In order to reduce the atmospheric pollution emitted by automobiles, control devices are being incorporated in the vehicles in many countries. This has resulted in a reduced vehicle mileage to the extent of about fifteen percent. Without the introduction of new technology, any further reduction in emission levels would be expected to extract payment in the form of further fuel economy losses. I...

An Oxy-hydrocarbon Model of Fossil Fuels

This paper asserts a new method of analyzing fossil fuels, useful for sorting coals into well defined categories and for the identification of outlying ultimate analysis data. It describes a series of techniques starting with a new multi-variant approach for describing the lower Ranks of coal, progressing to a classical, but modified, single-variant approach for the volatile and high energy Ran...
