Chemical interaction of closely located reactive particles in gas flow

The overall aim of this study is to contribute to the development of a new technique to reduce soot formation in entrained flow gasification process through the development of a high performance computer simulation tool. The starting point for the development is an assumption that chemical interactions among fuel particle are responsible for soot reduction. However, it is hard to prove experimentally because of the lack of high resolution in-situ measurement techniques.

This project aims at elucidating chemical interaction of fuel particles with highly resolved numerical simulation in order to reveal why forced particle dispersion can reduce soot formation. Since no existing numerical platform is suitable for this aim, the project will focus on constructing a numerical platform of closely located reactive particles in gas flow. To make the project successful, computational load should be kept manageable while resolving microscale physical phenomena and having representative kinetic scheme. Major tasks of the project are:

1) establishment of highly resolved simulation platform of reactive particles in gas flow;

2) reduction of detailed kinetic schemes for soot formation in biomass flame; and

3) application of reduced kinetic scheme into particle simulation platform.

This project is supported by Swedish Research Council (2016-2019) and main participant is Thamali.
