Inertial Particles and Vortices: Implications for Cloud Flows

We study, using 2D direct numerical simulations, the effects of particle inertia on the condensation process in a vortical flow. We find that particle inertia has a small effect on both the overall condensation rate as well as the size distribution of particles. These particles represent water droplets in the turbulent flows that are convecting clouds. The simulations presented here are indicative, and should serve as proof of concept. More detailed simulations are being performed.
