Molecular Dynamics Simulations of Carbon Nanotubes in Liquid Flow available in PDF, EPUB and Kindle. Molecular dynamics (MD) simulation method is used to simulate the dynamics of nanotubes in liquid flow. This study was motivated by our experimental work on the fabrication and mechanical properties characterization of multi-walled carbon nanotube(MWNT)-high density polyethylene (HDPE) composites fabricated by a melt processing method. SEM and TEM pictures show that the nanotubes are dispersed in the polymer matrix in small aggregates, the size of which decrease with the shearing strength in the suspension. Three types of behaviors are addressed. First, a high aspect ratio nanotube is modeled as a flexible fiber and its dynamics in simple shear flow are simulated by coupling flexible fiber dynamics based on continuum mechanics, with drag forces on the nanotube obtained from MD simulations. Results show that curved nanotubes in simple shear flow become straight and aligned along the shearing direction. Calculations also show that the viscosity of a dilute nanotube suspension increases with nanotube aspect ratio (Ar) and volume fraction (V f). For Ar = 400 and V f =0.708%, the suspension viscosity is two orders higher than the suspending liquid, which is comparable to reported viscosity measurements. The results also show that suspension viscosity decreases as the initial curvature of the nanotube increases. Second, Dynamics of a short nanotube (Ar

Download and read online ebook Vortex, Molecular Spin and Nanovorticity write by Percival McCormack. This book was released on 2011-09-21. Vortex, Molecular Spin and Nanovorticity available in PDF, EPUB and Kindle. The subject of this book is the physics of vortices. A detailed analysis of the dynamics of vortices will be presented. The important topics of vorticity and molecular spin will be dealt with, including the electromagnetic analogy and quantization in superfluids. The effect of molecular spin on the dynamics of molecular nano-confined fluids using the extended Navier-Stokes equations will also be covered –especially important to the theory and applicability of nanofluidics and associated devices. The nanoscale boundary layer and nanoscale vortex core are regions of intense vorticity (molecular spin). It will be shown, based on molecular kinetic theory and thermodynamics, that the macroscopic (solid body) rotation must be accompanied by internal rotation of the molecules. Electric polarization of the internal molecular rotations about the local rotation axis –the Barnett effect – occurs. In such a spin aligned system, major changes in the physical properties of the fluid result.

This book was released on 2008. Molecular Dynamics Simulations and Microscopic Hydrodynamics of Nanoscale Liquid Structures available in PDF, EPUB and Kindle. In this thesis, issues pertaining to the dynamics of nanoscale liquid systems, such as nanojets and nanobridges, in vacuum as well as in ambient gaseous conditions, are explored using both extensive molecular dynamics simulations and theoretical analyses. The simulation results serve as ``theoretical experimental data' (together with laboratory experiments when available) for the formulation, implementation, and testing of modified hydrodynamic formulations, including stochastic hydrodynamics. These investigations aim at extending hydrodynamic formulations to the nanoscale regime. In particular, the instability, and breakup of liquid nanobridges and nanojets are addressed in details. As an application of the microscopic hydrodynamics, a heated-nozzle technique to generate and control nanojets is proposed. Both simulations and microscopic hydrodynamic modeling reveal the formation of a ``virtual convergent nozzle', which consists of a narrowing convergent liquid core within a growing evaporative sheath, by the nanojet itself inside the real nozzle. The diameter of the resulting ejected nanojet is much smaller than the diameter of the nozzle. By adjusting the temperature distribution of the real nozzle, the size and shape of the virtual nozzle are changed, which in turn changes the diameter and the direction of the ejected nanojet.
