Abstract

Thermal management is one of the major bottleneck to increasing performance in modern electronic devices ranging from transistors to smartphones and data centers. It is increasingly evident that performance in those applications are mainly limited by state-of-the-art thermal management systems. Many of thermal problems can be addressed through scalable thermal architectures, which exhibit unique combinations of properties not available in nature. In this talk, I will discuss avenues to design functional thermal architectures that are widely employed as high-surface conduits for fluid transport. Most engineered porous media with long-range order contain a nonzero defect density due to nanoscopic perturbations, process variance, and imperfections in the fabrication process, which are defined as grain boundaries that separate the well-ordered crystalline grains. In later part, I will discuss surface-dependent boiling by decoding the correlations between interface dynamics and thermal performances, through the use of up-to-date machine learning techniques. This talk aims to illustrate how we can push toward the extreme limits of thermal technologies by designing the architectures of thermal materials.


Biography

Dr. Yoonjin Won is an Assistant Professor at the University of California at Irvine in mechanical and aerospace department. Dr. Won's research focuses on gaining fundamental insights into nanoscale phase change physics by linking thermal performances and interfacial phenomena with the demonstration of innovative materials, by conceptualizing artificial intelligence techniques. My research efforts aim to bring transformational efficiency enhancements in energy, water, transportation and electronics cooling by fundamentally manipulating liquid-solid interactions across multiple length and time scales. Dr. Won is selected as an NSF CAREER awardee in 2018 and has also received several awards including the ASME EPPD Early Career Award 2018, ASME EPPD Women Engineer Award 2020, UCI Samueli Career Development Fellowship, UCI New Faculty Teaching Academy Excellence, IEEE service award, and numerous best papers and poster awards from conferences. Dr. Won delivers keynote presentations at conferences including ASME International Conference on Nanochannels, Microchannels and Minichannels. Additional details for Dr. Won and her research group are available online (won.eng.uci.edu).
