The accurate prediction of solid pulverized fuel combustion is still a significant challenge. Therefore, performing so-called “Numerical Experiments” such as direct numerical simulations (DNS) as an established tool to study fundamental aspects of combustion by resolving the smallest turbulent scales is crucial to produce reduced-order models in the combustion of solid pulverized fuels. In the scope of this project, the aim is to design a co-flow jet of the solid pulverized fuel flame using a set of preliminary cases with simpler configurations and under-resolved resolution to determine the best configuration parameters and perform scaling tests required for the full-scale jet simulations. The simulations will be performed based on an Eulerian-Lagrangian framework developed in an in-house code CIAO, which is a high-order semi-implicit finite difference multi-physics solver and has been demonstrated to be suitable for massively parallel computations.
