Dr. Lingnan Lin, assistant professor, department of mechanical engineering, University of Maryland, College Park, will be visiting this Friday, May 2, to give a seminar. Please see abstract and biography below.
Abstract:
Two-phase flow boiling or condensation is one of the most efficient ways for heat
transfer, yet its underlying physics are complex and elusive. This lack of understanding
has impeded the design and control of heat transfer devices in many energy-intensive
applications, such as HVAC and electronics thermal management. Today, the growing
demand for high-power AI chips is accelerating the data center industry's transition from
single-phase air or liquid cooling to two-phase cooling, which further highlights the need
for improved modeling and measurement techniques. In this seminar, Dr. Lin will share
their recent efforts to better understand, model, and measure two-phase heat transfer,
including flow boiling and condensation. Specific topics include: (1) a new theoretical
model for two-phase heat transfer that works for both flow condensation and
evaporation; (2) flow boiling mechanisms in microfin tubes; (3) a universal correlation for
flow boiling heat transfer in microfin tubes, developed using a unique neural network; (4)
experimental measurement of two-phase flow and heat transfer.
Biography:
Dr. Lingnan Lin is an assistant professor at the University of Maryland, College Park.
Previously, he was a research scientist at the National Institute of Standards and
Technology (NIST), where he initially trained as a visiting Ph.D. student and later as a
postdoctoral research associate. He earned his Ph.D. from Shanghai Jiao Tong
University in 2018 and B.E. from the University of Science and Technology of China in
2013. Dr. Lin’s research is focused on fundamental phase-change heat and mass
transfer, with applications to energy transport, conversion, and storage. He is a member
of ASME and ASHRAE and serves on many committees within these organizations.
Light refreshments will be provided.
