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 ...
The ignition delay was measured as the time from the calculation start until the maximum OH radical mass fraction was reached in Cantera batch reactor simulation. There was no reference to experimental data. Table 2 summarizes the numerical ignition onset definitions that were incorporated in solid ...
as well as experiments conducted in a state-of-the-art optically accessible prechamber. The derived model is able to reproduce both flow-related quantities (velocity and turbulence profiles, jet penetration) and the ignition delay time under different variations. This study also illustrates...
[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...
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 ...
In this work, the ignition delay time characteristics of C2 –C3 binary blends of gaseous hydrocarbons including ethylene/propane and ethane/propane are studied over a wide range of temperatures (750 – 2000 K), pressures (1 – 135 bar), equivalence ratios (φ = 0.5 – 2.0) and dilutions...
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, ...
Generally, the ignition delay time is higher in dual fuel combustion, as the gaseous fuel fraction reduces the oxygen concentrations within the spray region. In case of diesel-producer gas combustion, the gaseous fuel is characterised by a high inert content and ignition is even longer due to ...
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...
