Collision Coalescnece in an Entrainment Mixing Environment

Two important processes that occur in clouds are entrainment-mixing, the mixing of external dry and moist cloud air at the edges of a cloud and collision-coalescence, the process of droplets colliding with each other and merging together into a single, larger droplet. While high-resolution models have been used to explore both of these processes seperately, their interaction with each other remains to be explored. Working alongside researchers in Brookhaven National Laboratory's Cloud Processes Group, we are seeking to use Particle-Resolved Direct Numerical Simulation to understand this complex interaction and how it impacts the evolution of key microphysical properties.
