Computation of Turbulent Evaporating Sprays: Eulerian Versus Lagrangian Approach

A new Eulerian model for turbulent evaporating sprays is presented. It comprises droplet heating and evaporation processes by solving separate transport equations for the droplet's temperature and diameter. A Lagrangian approach, which we have discussed in detail on other occasions, is used in comparing the results of the new method. A comparison with experimental data shows that both approaches are successful in predicting the main features of turbulent evaporating sprays
