Numerical Simulations A block diagram showing different components of our new Lagrangian-EulerianLagrangian model for two-phase reacting turbulent flows. The interactions among the velocity field (represented by the Eulerian grid system), the chemical species (represented by the Lagrangian Monte Carlo particles), and the spray(represented by the Lagrangian droplets) are also shown.
