Can we save lives with thermodynamics? Nanoengineering and Thermofluids for the Water-Food-Energy Nexus
27 Apr 2017 | | Contributor(s):: David M. Warsinger
Climate change, degrading water resources, and economic and population growth are increasing the need for new science and technologies at the Water-Energy-Food Nexus. In enabling new and improved technologies to tackle these issues, new nanomaterials designed with systems-level thermodynamics is...
Radiative Heat Transfer at the Nanoscale
12 Dec 2016 | | Contributor(s):: Pramod Reddy
In this talk, I will describe ongoing efforts in our group to experimentally elucidate nanoscale heat radiation. Specifically, I will present our recent experimental work where we have addressed the following questions: 1) Can existing theories accurately describe radiative heat transfer in...
Heat Under the Microscope:
Uncovering the Microscopic Processes that Govern
04 Oct 2016 | | Contributor(s):: Austin Minnich
n this talk, I will describe our efforts to uncover the microscopic processes that govern thermal transport by phonons. In particular, I will describe how our advances in computation and experiment have enabled the first direct measurements of thermal phonon transmission coefficients at solid...
Computer Graphics Imagery for Motion Pictures and Commercial Advertising: The Achievement of Highly-Realistic Images
19 Aug 2011 | | Contributor(s):: Kenneth Torrance
The talk will review some of the underlying concepts from Radiation Heat Transfer that have now been implemented in synthetic images. In many cases, researchers in graphics have created algorithms that are many times faster and more detailed than the engineering algorithms from which they were...
Tutorial 2: A Bottom-Up View of Heat Transfer in Nanomaterials
23 Mar 2011 | | Contributor(s):: Timothy S Fisher
This lecture provides a theoretical development of the transport of thermal energy by conduction in nanomaterials. The physical nature of energy transport by two carriers—electrons and phonons--will be explored from basic principles using a common Landauer framework. Issues including the quantum...
Limits of Thermal Processes and their Implications on Efficient Energy Utilization
27 Oct 2010 | | Contributor(s):: Arunava Majumdar
About 90 percent of the world’s energy use involves thermal processes – thermal engines to generate mechanical power; heating and cooling in buildings; heating involved in manufacturing of steel, cement, glass, petrochemicals etc. To identify opportunities for improving current technologies or...
