Topic: Extraordinary Heat Transfer and Energy Conversion at Nanoscale
Speaker: Gang Chen, Carl Richard Soderberg Professor of Power Engineering
Time: 2:00-3:00pm, July 5 (Tuesday)
Venue: F310, Mechanical Building A
 
Abstract:
 
Heat transfer and energy conversion phenomena at nanoscale can differ significantly from that in macroscale. In this talk, I will start with a general discussion of nanoscale heat transfer and energy conversion processes, followed by a few examples of extraordinary heat transfer phenomena from our research. The first example will be how nanostructures can be exploited to reduce the thermal conductivity of materials for more efficient thermoelectric energy conversion. In opposite examples, I will discuss how we engineer heat conduction to turn polymers from poor thermal conductors to highly thermally conductive materials and to regulate thermal conductivity by temperature via first-order phase transition. I will also presents theory and experimental results that show thermal radiation heat transfer at nanoscale can exceed the blackbody radiation by three orders of magnitude. I will conclude by introducing DOE Solid-State Solar-Thermal Energy Conversion Center (S3TEC Center).
