Relaxons Heat Up Thermal Transport

Thermal Transport in Crystals as a Kinetic Theory of Relaxons

Thermal conductivity in dielectric crystals is the result of the relaxation of lattice vibrations described by the phonon Boltzmann transport equation. Remarkably, an exact microscopic definition of the heat carriers and their relaxation times is still missing: Phonons, typically regarded as the relevant excitations for thermal transport, cannot be identified as the heat carriers when most scat...

Thermal interfacial transport in the presence of ballistic heat modes

Spin-dependent heat transport and thermal boundary resistance

ii Acknowledgments I have had the pleasure of working with many exceptional people during my time at Carnegie Mellon University. First and foremost, I wish to heartily thank my advisor, Professor Jimmy Zhu, for the chance to pursue my graduate studies under his guidance and instruction. He served the chair of the committee for my thesis. I wish to acknowledge the assistance and advice of my the...

thermal radiation heat transfer effects on single fuel droplet heat up considering it’s internal circulation

high temperatures are often encountered in almost all of the combustion systems, therefore, thermal radiation heat transfer can influence the droplets heat up rate and consequently their life time. in this paper, the effect of thermal radiation heat transfer is investigated for two cases of directional and spherically symmetric illuminations. the flow and temperature fields insdie and outside o...
