RÉSUMÉ

Numerical calculations of nonevaporating and evaporating sprays are reported and compared with experimental results that hare been previously reported in the literature. The Eulerian formulation for the gas field equations and the Lagrangian formulation for the droplet field equations are used together with the stochastic approach accounting for the effect of turbulence on the droplet motion. A numerical procedure using multicomputational domains is applied to cover the physical space until the required locations. The air entrainment at the free boundary of the jet spray is implicitly calculated in the solutions. All the spray predictions are compared against experimental data. It is shown that the predicted results satisfactorily follow the experimental measurements.
