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