Finite element model for turbulent spray combustion
Abstract
A finite element model for the prediction of spray flame field is presented. An Eulerian-Lagrangian approach is employed to model the reacting flow field of a spray combustor. The unsteady axisymmetric gas-phase equations are presented in Eulerian coordinates and the liquid-phase equations are formulated in Lagrangian coordinates. Turbulence is represented by the k-sigma model, and the reaction rate is determined by the modified eddy break-up model. Numerical results for the droplet trajectories and the effects of the evaporation models are discussed.
