A report describes direct numerical simulations of a droplet-laden mixing layer (e.g., evaporating droplets of a hydrocarbon fuel in air) undergoing a transition to mixing turbulence. The governing equations are those of Lagrangian transport of discrete droplets through a flowing gas, which is represented by Eulerian equations with source terms for two-way couplings of mass, momentum, and energy among the liquid, vapor, and carrier-gas phases. The equations are solved numerically, using as many as 18 × 106 grid points to discretize the Eulerian gas-phase equations and tracking as many as 5.7 × 106 evaporating droplets of various initial sizes in the Lagrangian reference frame.
