Particle motion and combustion in turbulent flows


The simulation of solid fuel combustion systems relies on the resolution of particle trajectories within the fluid domain. The widely used RANS approach to solving the fluid properties of a turbulent flow only resolves time-averaged quantities, which are not representative of the forces applied to the particle trajectories.

Modelling investigations are required to improve methods that apply turbulent fluctuations in the velocity field to the particle motion, as well as methods to resolve gas species concentrations on the heterogeneous reactions of combusting particles, and can be applied to CFD calculations of combustion facilities.
