Green-Kubo relation for viscosity tested using experimental data for a 2D dusty plasma
Yan Feng, J. Goree, Bin Liu +1
The theoretical Green-Kubo relation for viscosity is tested using experimentally obtained data. In a dusty plasma experiment, micron-size dust particles are introduced into a parti…
Accurate particle position measurement from images
Yan Feng, J. Goree, Bin Liu
The moment method is an image analysis technique for sub-pixel estimation of particle positions. The total error in the calculated particle position includes effects of pixel locki…
Rapid heating and cooling in two-dimensional Yukawa systems
Yan Feng, Bin Liu, J. Goree
Simulations are reported to investigate solid superheating and liquid supercooling of two-dimensional (2D) systems with a Yukawa interparticle potential. Motivated by experiments w…
Identifying anomalous diffusion and melting in dusty plasmas
Yan Feng, J. Goree, Bin Liu
Anomalous diffusion in liquids and the solid-liquid phase transition (melting) are studied in two-dimensional Yukawa systems. The self-intermediate scattering function (self-ISF),…
Viscosity calculated in simulations of strongly-coupled dusty plasmas with gas friction
Yan Feng, J. Goree, Bin Liu
A two-dimensional strongly-coupled dusty plasma is modeled using Langevin and frictionless molecular dynamical simulations. The static viscosity and the wave-number-dependent v…
Errors in particle tracking velocimetry with high-speed cameras
Yan Feng, J. Goree, Bin Liu
Velocity errors in particle tracking velocimetry (PTV) are studied. When using high-speed video cameras, the velocity error may increase at a high camera frame rate. This increase…
