Seminar - Nanoscale Heat Transfer and Energy Conversion by Prof. Gang Chen
Date: 14 October 2013 (Monday)
Time: 4:00 pm - 5:00 pm
Venue: Y302, The Hong Kong Polytechnic University
In this talk, I will use examples from our research to emphasize the intersects of nanocale heat transfer with fundamental physics, materials, and applications. I will discuss ballistic and coherent heat conduction in nanostructures leading to breakdown of the Fourier heat conduction law, near-field thermal radiation exceeding the Planck blackbody radiation law by 3-4 orders of magnitude, and the convergence of heat conduction and thermal radiation at nanoscale. By exploiting nanoscale heat transfer effects, materials with low thermal conductivity for thermoelectric energy conversion and plastic with high thermal conductivity are developed. Recently developed solar thermoelectric energy conversion devices will be discussed.
Dr. Gang Chen is currently the Carl Richard Soderberg Professor of Power Engineering and Mechanical Engineering Department Head at Massachusetts Institute of Technology. He obtained his Ph.D. degree from UC Berkeley in 1993 working under then Chancellor Chang-Lin Tien. He was a faculty member at Duke University (1993-1997), University of California at Los Angeles (1997-2001), before joining MIT in 2001. He is a recipient of the NSF Young Investigator Award, the ASME Heat Transfer Memorial Award, the R&D100 Award, and the MIT McDonald Award for Excellence in Mentoring and Advising. He is a member of the US National Academy of Engineering, a Guggenheim Fellow, an AAAS Fellow, and an ASME Fellow. He has published extensively in the area of nanoscale energy transport and conversion and nanoscale heat transfer. He is the director of Solid-State Solar-Thermal Energy Conversion Center funded by the US DOE’s Energy Frontier Research Centers program.
