“…The calculated activation energy shows a slight discrepancy and the results show a slight difference to the experiment (see Figure 4). A comparison between the calculated and experimental data indicates that the kerosene activation energy approximates that of ethylbenzene, which is different from the activation energy of n-decane and kerosene predicted by Dagaut and Cathonnet [11]. The study shows that the ignition delay time of kerosene is between that of aromatics and alkanes.…”

Shock tube study on auto-ignition characteristics of kerosene/air mixtures

et al. 2011

Ignition delay times are obtained for kerosene/air mixtures behind the reflected shock waves at temperatures between 1445 and 1650 K, at a pressure of 0.11 MPa and an equivalence ratio of 1.0. A nebulization device with Laval nozzle is used to nebulize kerosene and form an aerosol phase, which evaporates and diffuses rapidly behind the incident shock waves. Mixtures auto-ignite behind the reflected shock waves. An ICCD is used to visualize the kerosene/air mixture's ignition characteristics. The mixture's ignition intensity increases with increase in initial temperature. Continuous and irregular flames exist below 1515 K while plane and discontinuous flames exist over 1560 K. Ignition delay times decrease with increase in initial temperature. Experimental data shows good agreement with results reported previously in the literature. A new surrogate (consisting of 10% toluene, 10% ethylbenzene and 80% n-decane) is proposed for kerosene. Honnet et al.'s mechanism is used to simulate the ignition of kerosene with calculations agreeing well with the experimental data. The sensitivity of reaction H+O 2 <=>OH+O, which shows the highest sensitivity to the ignition delay time, increases with an increase in temperature. The chain breaching reaction of CH 3 with O 2 accelerates the total reaction rate and the H-atom abstraction of n-decane controls the total reaction rate. The rate of production and instantaneous heat production indicate that two reactions, H+O 2 <=>OH+O and O+H 2 <=>OH+H, are the key reactions to the formation of OH radicals, as well as the main endothermic reaction. However, the reaction of R3 is the main heat release reaction during ignition. Flame structure analysis shows that initial pressure is increased slightly as CO and H 2 O will appear before main ignition. Kerosene, a common hydrocarbon, is used as a fuel in aerospace applications, as a solvent, and for lighting. In the aerospace field, kerosene is a preferred fuel for scramjets and pulsed detonation engines (PDE) because of its stable thermodynamic properties and high calorific value. Investigation of the ignition delay time of kerosene is important for improving its combustion efficiency, increasing heat efficiency and reducing pollutants. Fuel residence times in the scramjet and PDE are very short, and of the same order of magnitude as ignition delay times. Therefore, ignition delay times strongly influence heat generation rates. The ability to control the kerosene's ignition delay time is *Corresponding author (email: zhhuang@mail.xjtu.edu.cn) crucial in combustor design and to ensure efficient combustion [1]. Kerosene composition is complex, making it difficult to investigate its ignition delay time. In recent years therefore, many researchers have focused on simulating the behavior of kerosene by using surrogates. Kerosene combustion mechanisms contain hundreds of species and thousands of elementary reactions, requiring extended computational times when using CFD software. A reduced number of reactions in mechanisms is required to decr...

“…The heptane pyrolysis products which have been obtained in previous conditions of pyrolysis and for different pyrolysis temperatures (800 K to 1000 K) have been studied with air at the stoichiometry under a constant pressure of 2 bars in premixed configuration ( Figure 13) with detailed combustion mechanism (kerosene combustion modelled by decane thanks to Dagaut and Cathonnet mechanism, 207 species and 1592 reactions [27]). The ignition time and the final flame temperature are mainly dependent on the initial combustion temperature and not on the initial composition.…”

Large heat load are encountered in hypersonic flight applications due to the high vehicle speed (over Mach 5, i.e. 5000 km.h-1) and to the combustion heat release. If passive and ablative protections are a way to ensure the thermal management, the regenerative cooling is probably the most efficient one to enable the structures withstanding (notably for reusable structures). The present study is a part of COMPARER project (COntrol and Measure of PArameters in a REacting stReam) which aims at investigating the highly coupled phenomenon (heat and mass transfers, pyrolysis, combustion) in a cooling channel surrounding a SCRamjet combustion chamber and at proposing some parameters to enable the control of such a complex technology. In this paper, we present the comparative numerical pyrolysis study of some selected synthetic and jet fuels (heptane, decane, dodecane, kerosene surrogate). The fluid pyrolysis has been studied experimentally and the results of RESPIRE numerical simulation under lab and in-flight conditions are given with validation to provide a deep understanding of phenomenon. The impact of the density, of the critical parameters, of the viscosity and of the chemistry is investigated to analyze their effect on the cooling efficiency of the engine. That also enables to estimate which properties the best cooling fuel should have. Furthermore, a combustion study is conducted because the cooling fuel is the one that ensure the thrust. The RESPIRE code enables to conduct both coupled pyrolysis and combustion studies. A first approach of the dynamic regeneratively cooled SCRamjet is provided to get a large vision of the fuel nature impact on the system.

“…For approximation the theoretical models to real applications it is advisable to take into account the dependence of k 0 and E on the temperature. It is known [12,13] that this feature is important at the local heating of small droplets, thin films and large amounts of liquid condensed substances by sources with limited power consumption. The similar task requires special consideration.…”

Abstract.A numerical research was executed for macroscopic regularities determination of heat and mass transfer processes under the conditions of phase transformation and chemical reaction at the ignition of vapour coming from fabrics impregnated by typical combustible liquid into oxidant area at the local power supply. Limit conditions of heterogeneous system "fabric -combustible liquid -oxidant" ignition at the heating of single metal particle was established. Dependences of ignition delay time on temperature and rates of local power source were obtained.
