Ignition delay time is the time it takes for a homogenous mixture at some given initialtemperature and pressure to ignite. This ignition delay time can be defined in a variety of ways,but it is often defined as the time at which the time derivative of temperature, pressure, or aspecific sp...
The ignition delay times predicted using DKM are validated with those reported in the literature. Furthermore, the CANTERA freely propagating 1D flame code is used in conjunction with the chemical kinetic mechanism to predict the laminar burning speeds for GTL fuel over a wide range of operating ...
[13] investigated the effect of nanosecond pulse discharge plasma on the ignition delay time and flame characteristics of ammonia over a wide range of reduced electric fields, pulse energy density, mixture temperature and composition by coupling the ZDPlasKin and Cantera codes. The results show that...
Next, the ignition delay time is defined. The influence of the CO/H2 ratio on the main chamber combustion initiation is investigated. To further understand the effects of fuel reactivity on hot jet ignition, the local temperature of the hot gas, important chemical reactions and pre-chamber fuel...
Cantera plug-in for Matlab/Simulink (Goodwin and Moffat2001) was employed to obtain the chemical reactions and the species thermodynamic properties. While no significant heat is released during the ignition delay time, chemical reactions do take place and a pool of radicals, which trigger the ...
The ignition delay time is predicted in agreement with the experiments by the three-dimensional simulations. The mechanism of mild ignition is analysed by Lagrangian tracer particles, tracking temperature histories of material particles. We observed strongly increased temperatures in the core region away ...
First, ignition is investigated at different ambient temperatures in 0D and 1D studies in order to isolate the effect of chemistry and chemical mechanism selection to ignition delay time (IDT). Second, 3D LES of SF and DF sprays at three different ambient temperatures is carried out. Third, ...
15 DRMs were selected with a view to assessing their ability to predict experimental IDTs with Cantera code and constant volume reactor model assumptions. As some research groups provided DRMs that were designed in a hierarchical way, the Pearson linear correlation coefficient was calculated for each...
model for two diesel fuel surrogates formulated from four components ( n -Hexadecane, Heptamethylnonane, Decahydro-naphthalene, and 1-Methyl-naphthalene) as a function of temperature and pressure, obtained by simulation in an adiabatic, homogeneous and constant pressure reactor using the Cantera ...
To our knowledge, the ignition delay measurements of butanol at these high pressures are the first of their kind. CH emission and pressure time histories have been probed to determine ignition delay times for all experiments. For stoichiometric fuel鈥揳ir-mixtures the influence of the temperature ...
