A fully coupled, parallel approach for the post-processing of CFD data through reactor network analysis

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 mechanism (hundreds of species). The numerical algorithm is based on a fully-coupled technique, in which the highly non-linear mass balance equations are solved together, by alternating different resolution methods in order to ensure high accuracy and fast eywords:
