Common definitions for ignition delay time are often hard to determine due to the issue of bifurcation and other non-idealities that result from high levels of CO 2 addition. Using high …
Ignition delay times of four different primary reference fuels (PRF), mixtures of n-heptane and iso-octane, were measured behind reflected shock waves in a high-pressure shock tube …
In this work, the effects of pre-ignition energy releases on H 2 single bondO 2 mixtures were explored in a shock tube with the aid of high-speed imaging and conventional pressure and …
High-temperature methane and propane laminar flame speed measurements were conducted behind reflected shock waves in a shock tube. A high-power Nd: YAG laser was …
Here, we propose a new physically consistent modeling scheme, JIHT-OHex (C x H y), that accurately predicts the formation and consumption of electronically excited …
Experimental and computational investigations are carried out to identify the generalized criterion to predict the preignition tendency of methanol and ethanol mixtures in shock tubes …

The oxidation of ethanol was investigated in shock tubes by measuring ignition delay times and water time history profiles. A laser absorption technique was used in the latter case …
Understanding premature ignition or preignition is of great importance as this phenomenon influences the design and operation of internal combustion engines. Preignition leading to …
The flame speeds of premixed stoichiometric n-heptane/21% O 2-79% Ar (so-called “airgon”) flames with different extents of pre-flame auto-ignition chemistry were …
