Near-Field Radiative Energy Exchange Analysis of Nanospheres and Nanorods: Space Waste Heat Recovery Device Design
(2011)
In the present study, a theoretical method for sphere-to-sphere radiative heat exchange is
implemented for silica, lithium fluoride, and arsenic triselenide nanospheres of equal and
unequal radii. The method is extended ...
Thermal conductances of aligned structures and thin films with embedded carbon nanotubes
(2012)
Individual carbon nanotubes (CNTs) have superior thermal conductivity than conventional materials. The applications for CNTs range from heat sinks, thin films to thermal interface materials. However, when CNTs are grouped ...
Simulations of Adsorption and In-plane Ordering of Electrostatically Adsorbed Charged Colloidal Nanoparticles
(2016-04-22)
Self-limiting assembly of nanoparticle arrays promises to revolutionize compliant device fabrication by enabling print-on-demand. Presently, quantitative understanding of the relationship between the array order, nanoparticle ...
Simulation of Shielding Materials against Galactic Cosmic Rays
(2017-04-18)
Radiation is one of the most critical hazards for deep space missions. Among the sources of deep space radiation, the Galactic Cosmic Rays, which are composed of high energy ions travelling at relativistic speeds from ...
Combined Convection of Packer Fluid Flow between Vertical Parallel Plates
(2017-04-20)
Packer fluid whose function is to prevent or tremendously reduce the heat transfer rate which would occur from the production tubing area to the production casing region is being studied in recent decades because of its ...
Improving Small Scale Cooling of Mini-Channels using Added Surface Defects
(2013-09-16)
Advancements in electronic performance lead to a decrease in device size and an increase in power density. Because of these changes, current cooling mechanisms for electronic devices are beginning to be ineffective. ...
Carbon nanotubes thermal conductivity analysis using molecular dynamics simulations
(2010)
Non-equilibrium molecular dynamics simulations are used to determine the thermal conductivities of (5,5) single wall carbon nanotubes. By fixing the temperatures of opposing ends of an armchair single wall carbon nanotube ...

(2014-01-29)
This dissertation provides a detailed description of a new thermal lattice Boltzmann model capable of simulating temperature and velocity gradients within micro/nano-channels and vertical cavities in rarefied flow extending ...
Temperature and Heat Flux Dependence of Thermal Resistance of Water/Metal Nanoparticle Interfaces
(2014-11-10)
Non-equilibrium Molecular Dynamics (MD) simulations of heat transport through nanoscale metallic systems in contact with water are performed to investigate the effects of temperature and heat flux on thermal resistance ...
Thermal Conductivity of Single Wall Carbon Nanotube and Copper Coaxial Nanocomposite
(2014-01-09)
Based on non-equilibrium molecular dynamics, a model is developed to study the thermal conductivity of Single Wall Carbon Nanotube (SWCNT) inside filled with Copper (Cu), forming a coaxial composite in the form of a nanowire. ...
