Two Win Best Poster Awards

Dec. 16, 2019 - Two graduate students won poster awards at recent American Society of Mechanical Engineers (ASME) conferences. Both students, Jonggyu Lee and Youngjoon Suh, are advised by Yoonjin Won, assistant professor of mechanical and aerospace engineering.

Suh won the 2019 Best Poster Award at the International Conference for Nanochannels, Microchannels and Minichannels in June. His poster addressed “Microstructural Patterning of Self-Assembled Colloidal Particles.”

“The physics that occur at the microscale is very different from what we experience in our everyday lives. We anticipate our results to provide significant insights toward fabricating perfectly ordered micro/nanostructures which can utilize the unique phenomena occurring at such scales to improve existing performances of cooling devices,” said Suh.

Lee earned third place out of nearly 100 posters in the 2019 Nasser Grayeli Best Student Poster Awards category at the International Technical Conference and Exhibition on Packaging and Integration of Electronic and Photonic Microsystems (InterPACK) in October. His poster was titled “Condensation Heat Transfer on Hierarchical Copper Inverse Opals.”

“Understanding the condensation on superhydrophobic surfaces is of great interest due to its importance for thermal management of high power-density electronics, dew harvesting, desalination and power generation plants,” explained Lee. “Our study demonstrates the potential of the hierarchically structured surfaces on condensation heat transfer by lowering thermal resistance through efficient droplet-jumping phenomena.”
