TUCSON, Ariz. (June 21, 2011) -- The U.S. Department of Defense (DOD) has awarded two grants to University of Arizona College of Engineering researchers for high-tech, specialized measuring equipment that can be used in real-world chemical engineering and civil engineering applications. The University of Arizona captured five of the 165 grants awarded nationwide.
UA College of Engineering awardees are Armin Sorooshian of the Department of Chemical and Environmental Engineering and Jennifer Duan of the Department of Civil Engineering and Engineering Mechanics, both proposing unique measurement methodologies.
Sorooshian's project examines water droplets in clouds for residual particles to determine their effect on precipitation and visibility. The project will develop and deploy in the field a tube-like aircraft inlet that can sample cloud droplets and dry them down, leaving only the residual particles that were the original seeds of the drops.
Examining the physical and chemical characterization of these particles enhances knowledge of how atmospheric aerosol particles affect clouds, precipitation, and visibility, Sorooshian said. The research team will use a U.S. Navy aircraft based near Monterey, Calif., to test this new tubular inlet device. The device is also expected to enhance the value of other instrumentation on the same aircraft downstream of this inlet, as the various characteristics of the cloud particles become better known.
The project -- which goes into the field for testing beginning July 1 -- is projected to not only improve the knowledge base related to the physicochemical nature of cloud droplets, but will educate engineering students involved in the study in the areas of instrument design and characterization, field measurements and analyzing scientific data, Sorooshian says.
Duan's civil engineering project earned support from the DOD's Army Corps of Engineers for its unique ability to study dam
