High resolution digital holographic synthetic aperture applied to deformation measurement and extended depth of field method [PDF]

open access: yes, 2010
This paper discusses the potential of the synthetic-aperture method in digital holography to increase the resolution, to perform high accuracy deformation measurement, and to obtain a three-dimensional topology map.

Modeling Anisotropic Transport in Polycrystalline Battery Materials

open access: yesBatteries, 2023
Hierarchical structures of many agglomerated primary crystals are often employed as cathode materials, especially for layered-oxide compounds. The anisotropic nature of these materials results in a strong correlation between particle morphology and ion ...

A simple method for fabricating phase-shifted fibre Bragg gratings with flexible choice of centre wavelength [PDF]

open access: yes, 2009
A simple technique for fabricating phase-shifted fibre Bragg gratings (PSFBGs) without the use of a phase-shifted phase mask is presented. Two, 3-mm long, standard fibre Bragg gratings (FBGs) were inscribed sequentially in singlemode fibre at the same

Experimental and Simulation Study on the Effect of Reduction Pretreatment on the Void Healing of Heavy Plate

open access: yesMetals, 2022
In addition to eliminating voids in a billet, the reduction pretreatment (RP) process can refine the austenite structure after reheating and can deform the residual voids, which affect the void healing behavior during insulation before rolling, and then ...

Pore-Scale Numerical Simulation of CO2–Oil Two-Phase Flow: A Multiple-Parameter Analysis Based on Phase-Field Method

open access: yesEnergies, 2022
A deep understanding of the pore-scale fluid flow mechanism during the CO2 flooding process is essential to enhanced oil recovery (EOR) and subsurface CO2 sequestration. Two-phase flow simulations were performed to simulate the CO2 flooding process based

Modelling of Effective Permeability Coefficient Caused by the Formation of CO2 Hydrate in Sand Layer Using Pore-Scale Numerical Simulations

open access: yesJournal of MMIJ, 2021
Carbon dioxide capture and storage is an efficient technology to reduce CO2. Among CO2 storage methods, storage in the form of gas hydrate is thought to be promising for increasing the volume capacity of storable CO2.

Bubble flow analysis using multi-phase field method [PDF]

open access: yesEPJ Web of Conferences
In simulations of gas-liquid two-phase flows using conventional interface capture methods, we observed that when bubbles come close to each other, they tend to merge numerically, despite experimental evidence indicating that they would repel each other ...

Numerical simulation on the freezing of deposited or impinged water droplets on a cold surface

open access: yesJournal of Thermal Science and Technology, 2021
The freezing of water droplets deposited or impinged on cold surfaces causes many problems in traffic lights, power transmission wires and heat exchangers. Thus, the suppression of the freezing of these droplets is very important.
