Turbulent spray combustion using finite elements

Conference ·
OSTI ID:5649435
; ;

A finite element model for the prediction of spray flame field is presented. A Eulerian-Lagrangian approach is employed to model the reacting flow field of a spray chamber. Turbulence is represented by the k-epsilon model, and the reaction rate is determined by the modified eddy-break-up model. The vaporization phenomena is modeled by Ranz and Marshall formula. Numerical results for the droplet trajectories, the evaporation, and the recirculation characteristics are discussed. 10 refs.
