Numerical study of eddy current by Finite Element Method for cracks detection in structures

open access: yesFracture and Structural Integrity, 2016
In this paper, we try to use the finite element method of 2-D axisymmetry to solve problems in eddy current testing problems where the main idea is detecting crack's shape using the NDT-EC.

Compaction‐Driven Convection in the Growing Inner Core

open access: yesGeophysical Research Letters
The Earth's inner core (IC) is known to exhibit heterogeneous structures with their origins still unknown. From the onset of nucleation, the IC can grow via sedimentation and compaction of iron crystals freezing out from the fluid outer core.

Roles of non-axisymmetric perturbations in free drift vertical displacement events on EAST

open access: yesNuclear Fusion
The safe operation of most tokamaks, especially the large ones, relies on the feedback control of vertical displacement events (VDEs). However, most of these feedback control systems are based on axisymmetric VDE models.

Effect of finite beta on neoclassical transport characteristics in CFQS quasi-axisymmetric stellarator

open access: yesJournal of Physics Communications
CFQS is the world’s first modular-coil-type quasi-axisymmetric stellarator, which is currently under construction. This study systematically investigates the effect of finite beta (volume-averaged beta, 〈 β 〉) on the neoclassical transport ...

Finite Element Analysis and Electrohydrodynamic Multiphysics Modeling of a Corona-Streamer Discharge in a Two-Phase Flow Medium

open access: yesEnergies
This study proposes an electrohydrodynamic multiphysics modeling and finite element analysis technique to accurately simulate corona-streamer discharges in a two-phase flow medium.

Schlieren visualisation and measurement of axisymmetric disturbances [PDF]

open access: yesNonlinear Processes in Geophysics, 2003
Synthetic schlieren is a new technique that allows one easily and inexpensively to visualise density variations, such as those caused by internal waves propagating in a density stratified fluid.

Partial persistence of memory in bubble breakup: Incomplete universality acquired by broken symmetry

open access: yesPhysical Review Research
When a water drop falls from a faucet, the drop is created with the formation of an axisymmetric constriction region, which thins down to breakup. Such formation of a fluid drop has been extensively studied as a representative of the singular dynamics ...

Wave extraction in axisymmetry

open access: yes
Implement wave extraction in the form of the higher-dimensional analogue of theNewman-Penrose scalar as developed in the recent literature. Test the extraction method for the case of head-on collisions of black holes starting from rest against other methods used to calculate the energy emitted in gravitational radiation.
