WP 1 leader: Nils Erland L. Haugen/PhD

Through many years of intense international research on turbulent gaseous combustion, the development within this field has been very good, and is today at an advanced level. This is, however, not the case for the field of turbulent combustion of solid fuels. This field is lagging behind by several decades compared to turbulent gaseous combustion.
The objective of this WP is to close parts of this gap by performing very detailed studies of
the coupling between reactive particles and a turbulent fluid. The main result should be an
increased understanding of the coupling, and a significantly better modelling capability.
This work will be based on work already done together with Stanford University, in particular through the WP leaders stay at Stanford in the period 2012-2013. This collaboration has resulted in a very detailed description of reactive particles and their coupling to the surrounding fluid [1-3], which is ready to be implemented into a DNS simulation tool.

This WP will be very closely linked with both WP2 and WP3. The experimental studies in WP2 will be done in parallell with WP1, and will be used to verify the numerical simulation
Tools developed in WP1. At the same time the results from WP2 will also be used to obtain a more fundamental understanding of the reactive particle-fluid coupling, which will then help guide the theoretical development in WP1. The results and fundamental understanding obtained in WP1 will eventually be used to develop and implement models for reactive particle-turbulence coupling in RANS and/or LES simulation tools in WP3. These models will then be the crucial ingredient for the full scale simulations performed in WP4.
