Non-sooting counterflow diffusion flames have been studied both computationally and experimentally, using either JP-8, or a six-component JP-8 surrogate mixture, or its individual components. The computational study employs a counterflow diffusion flame model, the solution of which is coupled with arc length continuation to examine a wide variety of inlet(More)
This paper presents the approach and the results of a kinetic generator in the area of hydrocarbon pyrolysis mechanisms. Radical formation and successive radical decomposition are taken into account. Care is paid to the description of molecule identification procedure and to its homomorphism which enables unique and no ambiguous reactions. New results(More)
Liquid feedstocks of ethylene crackers are complex hydrocarbon mixtures containing a huge number of different chemical species. Accurate characterization of petrochemical feeds plays a crucial role in describing the different reaction pathways and reactivity of the various isomer species. Thus, this knowledge becomes a need when it comes to develop(More)
In this paper we describe and apply a parallel code, named KPPSMOKE, for the prediction of pollutant emissions from combustion devices operating in turbulent conditions. The approach is based on the kinetic post-processing of CFD simulations, which are transformed into equivalent networks of perfectly stirred reactors and solved using a detailed kinetic(More)
Multi-scale process modeling is very appealing methodology for process optimization since it highlights certain issues that remain unexplored with conventional methodologies and debottlenecks certain potentialities that remain unexploited in chemical plants. In this work, a kinetic model with 2400 reactions and 140 species is implemented in a proper reactor(More)
The modeling of thermal reaction furnaces of Sulfur Recovery Units (SRUs) is a rather complex problem since it involves different modeling scales such as the kinetic/molecular scale, the reactor scale, and the chemical process scale. This work introduces the multi-scale modeling approach to characterize the kinetic and reaction engineering scales for the(More)
