Axisymmetric Grazing-Incidence Focusing Optics for Small-Angle Neutron Scattering
Atom and neutron optics X-ray optics small-angle neutron scattering
2012/5/17
We propose and design novel axisymmetric focusing mirrors, known as Wolter optics, for small-angle neutron scattering instruments. Ray-tracing simulations show that using the mirrors can result in mor...
From x-ray telescopes to neutron scattering: using axisymmetric mirrors to focus a neutron beam
atom and neutron optics x-ray optics Instrumentation and Detectors
2012/4/24
We demonstrate neutron beam focusing by axisymmetric mirror systems based on a pair of mirrors consisting of a confocal ellipsoid and hyperboloid. Such a system, known as a Wolter mirror configuration...
The axisymmetric long-wave interfacial stability of core-annular flow of power-law fluid with surfactant
Core-annular flow Power-law fluid Interfacial
2012/2/24
The long wave stability of core-annular flow of power-law fluids with an axial pressure gradient is investigated at low Reynolds number. The interface between the two fluids is populated with an insol...
Axisymmetric compressive buckling of multi-walled carbon nanotubes under different boundary conditions
Carbon nanotube Buckling Van der Waals forces
2012/2/24
The paper studies the axisymmetric compressive buckling behavior of multi-walled carbon nanotubes (MWNTs) under different boundary conditions based on continuum mechanics model. A buckling condition i...
EFFECT OF PRANDTL NUMBER ON HEAT TRANSFER CHARACTERISTICS IN AN AXISYMMETRIC SUDDEN EXPANSION: A NUMERICAL STUDY
turbulence Prandtl number heat transfer
2009/10/14
Using the standard k-e turbulence model, an incompressible, axisymmetric turbulent flow with a sudden expansion was simulated. Effect of Prandtl number on heat transfer characteristics downstream of t...
NUMERICAL MODELING OF DISPERSE MATERIAL EVAPORATION IN AXISYMMETRIC THERMAL PLASMA REACTOR
two-phase flow thermal plasma heat and mass transfer
2009/10/13
A numerical 3D Euler-Lagrangian stochastic-deterministic (LS(D) model of two-phase flow laden with solid particles was developed. The model includes the relevant physical effects, namely phase interac...

2009/10/10
A simple computational model is developed to estimate elastic, elastic-plastic, fully plastic, and residual stress states in generalized plane strain axisymmetric structures considering temperature de...
An Axisymmetric Infinite Cylinder with Two Cracks and a Rigid Inclusion
Axisymmetric Infinite cylinder Penny-shaped crack Rigid inclusion Stress intensity factor
2009/10/9
This work considers the analysis of a cracked infinite cylinder with a rigid inclusion. The material of the cylinder is assumed to be linearly elastic and isotropic. The ends of the infinite cylinders...
