Rare Metals, EarlyView.ABSTRACT The poor Zn chemistry of Zn metal anode and sluggish reaction kinetics of cathodes at high mass loadings are two crucial issues for hindering the application of aqueous Zn‐ion batteries (AZIBs). Herein, the hierarchical porous N‐doped carbon fibers (HPNCFs) were proposed to simultaneously optimize the reversibility of Zn plating/stripping of ...

Rare Metals, EarlyView.ABSTRACT Porous NiTi alloys are widely used in biomedical and engineering fields. Using the PBF‐LB technique, the TPMS and Voronoi porous parts with a porosity of ∼67% and a minimum feature size of 0.15 ± 0.02 mm were fabricated. Although the bulk sample fabricated with the same parameters is defect‐free, μ‐CT reconstruction on the porous sample ...

Numerical simulation of water waves interacting with elastic ice floes [PDF]
, 2020 摘要：本文围绕弹性冰群与波浪相互作用问题，建立了基于 OpenFOAM 开源软件的数值 计算模型，实现了流体与弹性浮冰耦合运动的双向迭代求解，并以规则波与两片弹性浮冰 的相互作用为例，分析了浮冰间距和浮冰刚度等参数对二维波浪传播特性的影响。研究发 现，在所考虑的参数范围内，刚度越大、间距越小的两块浮冰，对应的波浪反射系数越小、 透射系数越大，并且波浪反射系数的减小幅度大于透射系数的增加幅度。 关键词：OpenFOAM；流固耦合；浮冰；波物作用 ...

, 2018 为了确保油田开采过程中电潜泵在高含气油井的正常运行,结合气液分离技术和引射技术,该文运用CFD模拟软件FLUENT研究了一种高含气井下气液混合输送技术.该技术通过建立气体及液体分采通道,利用引射原理将增压后的高压动力液携带富气流举升至地面,以实现利用生产井自身流体实现自我举升.研究表明:经过对比分析发现,对于不同入口气体含量的工况,由于射流泵引射装置的引射比影响,入口气体体积含量40%是一拐点,当入口气体含量超过40%时,引管内的气相含量以及流速基本达到一定值;对于不同入口流量,随着流量的增加 ...

Rare Metals, EarlyView.ABSTRACT The similar physicochemical properties of alkali metal elements make the co‐enrichment and precise separation of Cs+ and Rb+ in complex brine systems highly challenging. Here, an all‐inorganic strategy is proposed, which achieves efficient enrichment and precise separation of Cs+ and Rb+ in high‐salt systems by constructing Sr2+/Ba2+‐based ...
