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 Conduction in a Slab X55T0 and Sub-cases
21 Feb 2014 | | Contributor(s):: Donald E. Amos
A slab is heated on both faces with known fluxes which are partly dissipated by conduction into the slab, partly lost to the exterior media, and partly stored in a boundary layer with only heat capacity. This description of each boundary condition is known as a Type 5 condition and in the...
1-D Green's Functions For Heat Conduction Between Semi-infinite Slabs With Perfect and Imperfect Boundary Contact
17 Sep 2012 | | Contributor(s):: Donald E. Amos
This document presents two derivations for 1-D Green's functionsfor semi-infinite slabs in contact along the boundary x=0. The case ofimperfect contact with a heat transfer coefficient h is derived and the caseof perfect contact is obtained by taking h to infinity. The two dimensionalcase with...

Theory of Heat Conduction for Two Region Problems Using Green's Functions
29 Mar 2012 | | Contributor(s):: Donald E. Amos
This paper derives equations which describe transient temperature distributions in adjacent regions which share a common boundary. These regions consist of materials with distinct, constant physical properties. The theory is developed for two types of boundary contact. The first formula is...
