ABSTRACT
Direct Numerical Simulations (DNS) of turbulent two-phase flows have been carried out to study the polydispersion of a vaporizing spray in a statistically stationary grid turbulence. The evolution of various droplet size classes has been studied. It exhibits different dynamical behaviors for droplets of different sizes. The results have been used to evaluate successfully a new Eulerian model which proves its capability to capture the polydisperse spray dynamics and vaporization.
