This paper presents a non‐iterative numerical technique for computing time‐dependent gas‐droplet flows. The method is a fully interacting combination of Eulerian fluid and Lagrangian particle calculations. The interaction calculations between the two phases are formulated on a pressure‐velocity‐coupling procedure based on the operator‐splitting technique. This procedure eliminates the global iterations required in the conventional particle‐source‐in‐cell (PSIC) procedure. Turbulent dispersion calculations are treated by a stochastic procedure. Numerical calculations and comparisons with available experimental data as well as efficiency assessments are given for some sprays typical of spray combustion applications.
