Advanced Deterministic Phonon Transport Techniques for Predicting Spectral Thermal Conductivity in Homogeneous and Heterogeneous Media

Creator:

Harter, Jackson R.

Abstract:

We present a deterministic spectral method to predict equilibrium temperature distributions, heat flux, and thermal conductivity in homogeneous and heterogeneous media. We solve the Boltzmann transport equation in a second order spatial, self-adjoint angular flux formulation. We implemented this method into the radiation transport code Rattlesnake, built using the MOOSE...

Simulations of geckos dry adhesion system

Creator:

Hu, Congcong

Abstract:

Simulation models were developed to explore the reversible nature of gecko dry adhesion system. The central idea of this model is that even with a small moment imparted on the contact tip, the seta can be easily ad-adhered. It is shown that this contact condition is very sensitive, but can...

Dissipation and wavepacket collision in carbon nanotube waveguides

Creator:

Saranam, Venkata Rajesh

Abstract:

Carbon nanotubes (CNTs) superior mechanical, electrical and thermal properties make them attractive components in nanomechanical devices. Their large aspect ratio and low density makes them ideal candidates for high frequency resonators in numerous applications including wireless communication, and mass and chemical sensors. One reason why CNTs have been slow to...

Interface Analysis of Titanium Dioxide and Graphene

Creator:

Frazier, Devon Paige

Abstract:

Titanium dioxide, in the anatase form, is a photocatalyst and has applications in water pollution reduction. Efficiency can be improved with a graphene substrate, which delays electron-hole recombination and may reduce the band gap. In this work, we determine if graphene can also act as a morphactant, changing the shape...
