Rapid evaporation and condensation of aerosols
From the delivery of drugs to the lungs, to the evaporation of fuel droplets in combustion, the spray drying of particles and the growth of particles in the atmosphere, understanding the rate at which particles can change size and composition is also crucial. For example, the processes occurring during the evaporation of a volatile solvent in the use of metered does inhalers critically determine the delivery of active pharmaceuticals to the lungs. The solid structures formed when liquid droplets rapidly evaporate are controlled by how quickly the solvent evaporates in spray drying. Studies of these very rapid evaporation/condensation processes are a further focus of our work.
