Summary of Flow Problem
Three-dimensional mixing layer: two parallel streams at different velocities, the interface is the mixing region
Spatial mixing layer: fixed region in space
Temporal mixing layer: follow a coherent structure in time
Initially, the lower stream is droplet-laden, the upper stream is droplet-free
As the layer evolves, it undergoes rollup and pairing and growth, entraining droplets
The carrier gas is hotter than the droplets, causing the droplets to evaporate
