Evaporation and collision of droplets play an important role in various industrial applications such as spray cooling, patterning, inkjet printing, and so on. Choi’s research has focused on the development of such tools, especially the advancement of microscopic optical techniques for examining droplet dynamics. This presentation will introduce two recent research results. The first topic is “Rebound phenomena during collision of water droplets impinging on a hemispherical static drop on solid surfaces”. The rebound regime of a droplet that impinges on a hemispherical static droplet deposited on two different solid surfaces was experimentally examined. The second topic is about “Natural evaporation of nanofluid droplets on glass surfaces.” Evaporation characteristics of Al2O3 nanofluid droplets such as total evaporation time, equilibrium contact angles and corresponding perimeters are experimentally investigated. The spatial non-uniformity from aggregation effect was observed, which may be an important factor to calculate effective conductivity of the nanofluids.
Chang Kyoung (CK) Choi is an assistant professor of Mechanical Engineering-Engineering Mechanics at Michigan
Technological University. Prior to this appointment in 2009, he was a post-doctoral researcher at Oak Ridge National Laboratory (ORNL) from Jan. to Dec. 2008. He received his B.S. and M.S. in Mechanical Engineering from Chung-ang University in 1999 and 2001, respectively. He received a PhD in Mechanical Engineering from the University of
Tennessee-Knoxville in 2007. Right after his doctoral graduation, he continued and expanded his research areas by working in three different fields of Mechanical Engr., Biomedical, Engr., and Biology as a post-doc in UT-Knoxville. His research interests are microscale heat transfer, micro-fluidics, micro-/nano-fabricaions, opto-electrical cellular sensing, droplet impingement on patterned metal surfaces, multiscale interface phenomena, and chemotaxis. He is particularly interested in developing a versatile and highly capable multimodality imaging system coupled with the culture platform in
order to make in vitro data collection even more comprehensive. He is currently a co-chair of committee on visualization of heat transfer (K-22) and a co-organizer of Photogallery-heat transfer visualization in ASME-IMECE.
