Non‐Markovian Quantum Kinetic Simulations of Uniform Dense Plasmas: Mitigating the Aliasing Problem

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Dense quantum plasmas out of equilibrium are successfully modeled using quantum kinetic equations, such as the quantum Boltzmann, Landau, or Balescu–Lenard equation. However, these equations do not properly take into account correlation effects, which require the use of generalized non‐Markovian kinetic equations.

Ground vibration isolation using mass scatters: A comparative study with trench barriers and wave‐impeding blocks

open access: yesDeep Underground Science and Engineering, EarlyView.
Ground‐borne vibrations are a frequent source of environmental problems. A full‐scale experiment is conducted to validate a 3D numerical model in order to analyze the efficiency of three methods of isolation. Trench barriers and wave‐impeding blocks are impractical and expensive methods of isolation, but mass scatters appear to be an efficient ...

Blasting effects of cross‐fault deep‐buried excavation on adjacent existing tunnel stability

open access: yesDeep Underground Science and Engineering, EarlyView.
Based on the theoretical analysis of cylindrical wave propagation in a deep rock mass in the fault with a filling layer, the calculation method of peak particle velocity caused by wave propagation in the existing tunnel is established. The viscoelastic characteristics of a rock mass are examined in the analysis.

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system

open access: yesDeep Underground Science and Engineering, EarlyView.
The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an

Annular two-phase flow in a small diameter tube: OpenFOAM simulations with turbulence damping vs optical measurements

open access: yesInternational Journal of Thermofluids
In this work, numerical simulations are performed to predict two-phase annular flow of refrigerant R245fa inside a 3.4 mm diameter vertical channel. The VOF (Volume of Fluid) method implemented in an OpenFOAM solver is used to accurately track the vapor ...
