Droplet Condensation/Evaporation
Atmospheric modeling, specifically of cloud physics, generally involves distances on the order of kilometers. However, many of the important physics involving water droplets’ evolution are dictates by microphysics on turbulence scales (millimeters). In order to accommodate the microphysics of droplet behavior on in a large-scale model, an analytical model is needed that accounts for the physics in a broad way.
In an attempt to develop a working modeling for droplet growth/evaporation, we are conducting experiments of a hot, humid jet of air issuing into a cooler, drier atmosphere. A PDPA is used to measure the droplet distribution at various locations throughout the jet. This data is used to help develop and validate our model.
