Equilibrium Molecular Dynamics Study of Heat Conduction in Octane
Fluids are important components in heat transfer systems. Understanding heat conduction in liquids at the atomic level would allow better design of liquids with specific heat transfer properties. However, heat transfer in molecular chain liquids is a complex interplay between heat transfer within a molecule and between molecules. This thesis studies the contribution of each type of atomic inter...
متن کاملMolecular Dynamics of Heat Conduction through Carbon Nanotube
The heat conduction along a single walled carbon nanotube (SWNT)[1-4] was simulated by the molecular dynamics method with the Tersoff-Brenner bond order potential [5,6]. One of the purposes of this study is to clarify the thermal conductivity of carbon nanotubes, which is speculated to be higher than any other material along the cylindrical axis. Very recently, measurements of thermal conductiv...
متن کاملA Molecular Dynamics Simulation of Heat Conduction in SWNTs
The heat conduction in finite length single walled carbon nanotubes (SWNTs) was simulated by the molecular dynamics method with the Tersoff-Brenner bond order potential [1]. Temperature at each end of a SWNT was controlled by the phantom technique, and the thermal conductivity λ was calculated from the measured temperature gradient z T ∂ ∂ / and the energy budgets in phantom molecules through t...
متن کاملMolecular dynamics simulation of heat conduction in near-critical fluids.
Using molecular dynamics simulations we study supercritical fluids near the gas-liquid critical point under heat flow in two dimensions. We calculate the steady-state temperature and density profiles. The resultant thermal conductivity exhibits critical singularity in agreement with the mode-coupling theory in two dimensions. We also calculate distributions of the momentum and heat fluxes at fi...
