3. Modeling method
CHEMKIN PRO [35] commercial package was used to perform
all the simulations presented in this work. The standard constant
internal energy and volume (constant UV) assumptions were used.
However, the facility-dependent pre-ignition pressure rise (dp/dt),
which is 3.5%/ms in our shock tube, is modeled as a change in the
volume in all the calculations presented in this work. The mechanism
developed by Serinyel et al. [1] was employed as the base
mechanism to simulate the 2-butanone oxidation as well as its
reaction with OH. Few modifications to this base mechanism were
made in order to improve it, as detailed in the subsequent sections.
There are no existing mechanisms for 3-buten-2-one except for a
few addition reactions of 3-buten-2-one with a number of radicals
are available in the base mechanism of 2-butanone. Therefore, a
detailed chemistry is developed here for 3-buten-2-one oxidation,
which was based on rate estimations and other assumptions, as described
in later sections.
