research includes two parts, the first one is about integrated
building systems for energy efficiency and renewable technologies.
He has determined the most energy efficient and cost effective
combination of architectural elements and mechanical systems to
specify in an Minneapolis office building while maintaining a
comfortable and healthy indoor environment for the occupants.
The current project is to
numerically determine the collision efficiencies for the electro
scavenging of aerosol particles by droplets. Cloud particles fall
through a population of atmospheric aerosol particles which collide
with the cloud particles and fall to the ground. This phenomenon is
defined as "scavenging" and can be used as a way of pollutant
control. When the two particles have opposite charge, the attraction
caused by the electrostatic force can greatly increase the
collection efficiency. In this study, a model has been developed to
predict the collection efficiencies of electro scavenging for the
larger collector droplets and the small aerosol particles.
