A fuel spray planar counterfiow flame has been modeled by means of a low-Mach-number boundary layer approach. The model considers density variations and full coupling between the two phases by means of a hybrid Eulerian-Lagrangian formulation, with droplet drag and vaporization. A spherically symmetric, unsteady droplet model with variable properties has been employed. Conditions for similarity in such a two-phase, particle-laden reacting boundary layer have been determined. Similarity solutions have been derived that are valid at any distance from the stagnation point and for any liquid fuel concentration and droplet number density within the limits of negligible particle-particle interactions. Results for the specific calculation of a monodisperse n-octane spray flame are reported and discussed.
