ADVANCING TWO-PHASE HEAT TRANSFER: THEORY, MODELING & MEASUREMENT

Mon, 28 Apr 2025 09:30:50 -0400

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.

We look forward to seeing you there!
