Large eddy simulation of droplet breakup in turbulent flow with adaptive mesh refinement

A series of turbulence-droplet interactions with realistic density ratios encountered in an aeroengine combustor are simulated and the effect of droplet size is investigated. It is shown that droplets present periphery shedding at the initial stage of breakup and are stretched into a disk-like shape before final breakup. The vortical turbulence helps to deform and break up the interface. The general turbulent characteristics are similar to single-phase flow and more perturbations are introduced by the gas-liquid interactions.
