综述 Review

A review of drag reduction by additives in curved pipes for single‐phase liquid and two‐phase flows

单相液体和两相流弯管中减阻添加剂综述

Paul O. Ayegba, Lawrence C. Edomwonyi‐Out, Nurudeen Yusuf, Abdulkareem Abubakar

A review of investigations on the effect of drag‐reducing agents in flows around curved pipes and bends is presented. Drag reduction in curved pipe flows are generally lower than in straight pipes and the mechanism is still not generally accepted. This review is a launch pad for future research as it highlighted some research gaps with appropriate recommendations.

本文综述了减阻剂在弯管和弯头周围流动中的作用的研究情况。弯管流动中的减阻作用一般低于直管,但研究者尚未做出合理的机理解释。这篇综述着重指出了一些研究之间的差别,并提出了适当的建议,可以作为未来研究的出发点。

1. Inverse functions for Monte Carlo simulations with applications to hitting time distributions

蒙特卡洛模拟的反函数及其在命中时间分布的应用

Avishai Ben‐David, Raghu Raghavan

We explore a well‐known probability (the F‐ratio distribution) as an alternative to generating look‐up tables and interpolations to obtain the required random time samples for hitting time distributions. Other Monte Carlo simulations in a number of fields of application may benefit from our method.

我们探索了一种众所周知的概率(F比率分布),用另一种方法生成查找表和插值,来获得命中时间分布所需的随机时间样本。同时,我们的方法可能有助于其他一些应用领域的蒙特卡洛模拟。

3. Fresh insights into detonation nanodiamond aggregation: An X‐ray photoelectron spectroscopy, thermogravimetric analysis, and nuclear magnetic resonance study

爆轰纳米金刚石聚集的新见解:X射线光电子能谱,热重分析和核磁共振研究

Khabiboulakh Katsiev Vera Solovyeva Remi Mahfouz Edy Abou‐Hamad Wei Peng Hicham Idriss Ahmad R. Kirmani

The mechanism behind aggregation in detonation nanodiamonds is outlined. Surface oxygen functionalities, identified as C-O-C species, cross‐link the primary particles (ca. 4‐5 nm) forming large polydisperse aggregates. A facile acid hydrolysis is proposed for de‐aggregating the diamonds in high yields.

概述了爆轰纳米金刚石中聚集的机理。初级颗粒(约4-5纳米)通过表面的含氧官能团(确定为C -O-C物种)交联,形成较大的多分散的聚集体。此外,提出了一种简便的酸水解方法,以使金刚石高产率地解聚。

Owusu Nyarko‐Boateng, Adebayo Felix Adekoya, Benjamin Asubam Weyori

This research presents a machine learning (ML) approach to predict the actual location of a fiber cable fault in an underground optical transmission link. Linear regression in the python sci‐kit learn library was used to predict the actual location of a fault in an underground optical network. The MSE and MAE evaluation matrix used provided good accuracy results of 0.061291 and 0.080143, respectively.

6. Hot‐cracking susceptibility of fully austenitic stainless steel using pulsed‐current gas tungsten arc‐welding process

采用脉冲电流气体钨氩弧焊工艺的全奥氏体不锈钢的热裂纹敏感性研究

Mohamed Abu‐Aesh, Mohamed Taha, Ahmed Salem El‐Sabbagh, Lutz Dorn

In the present study, the effects of pulse frequency, time ratio, and pulse current on the cracking susceptibility of austenitic stainless steel thin sheets are investigated. A fan‐shaped cracking test specimen is adopted, and suitable final dimensions are obtained by conducting some preliminary experiments. The results are found to be significantly improved when compared with those of the continuous‐current process, indicating that the pulsed‐current gas tungsten arc‐welding process (PCGTAW) has an effective role in reducing the hot‐cracking susceptibility.

本研究探讨了脉冲频率、时间比和脉冲电流对奥氏体不锈钢薄板开裂敏感性的影响。采用扇形开裂试验样品,通过一些初步实验得到合适的最终尺寸。与连续电流工艺相比,结果有明显的改善,表面脉冲电流气体钨氩弧焊工艺(PCGTAW)对降低热裂敏感性能够起到有效作用。

7. Using temporal convolution network for remaining useful lifetime prediction

利用时间卷积网络进行剩余使用寿命预测

Jungan Chen, Danjiang Chen, Gaoping Liu

Because of the inherently long‐term degradation process, it is necessary to learn temporal features from long history sequence data for remaining useful lifetime estimation. A temporal convolution network combining causal filters with dilated convolutions is hence used to expand the receptive field length of the network to improve prediction performance.

由于固有的长期退化过程,有必要从长历史序列数据中学习时间特征,以便进行剩余使用寿命的估计。因此,运用了因果滤波器与扩张卷积相结合的时间卷积网络,来扩大网络的接受场长度,从而提高预测性能。

8. Cross‐domain bearing fault diagnosis with refined composite multiscale fuzzy entropy and the self organizing fuzzy classifier

精细复合多尺度模糊熵和自组织模糊分类器的跨域轴承故障诊断

Esther W. Gituku, James K. Kimotho, Jackson G. Njiri

The use of refined composite multiscale fuzzy entropy (RCMFE) for cross‐domain diagnosis of bearings is here introduced and verified with two publicly available datasets. Compared to related works, the proposed approach does not require deep learning for feature extraction nor any domain adaptation technique as the RCMFE feature is robust against changing operating conditions. Furthermore, the method does not need target domain data during training.

本文介绍了精炼复合多尺度模糊熵(RCMFE)在轴承跨域诊断中的应用,并通过两个公开的数据集进行了验证。与相关工作相比,本文所提出的方法不需要深度学习进行特征提取,也不需要任何域适应技术,因为RCMFE特征对变化的工作条件具有鲁棒性。此外,该方法在训练过程中不需要目标域数据。
