Abstract

The study of erosion caused by turbulent flow of slurries is crucial for designing and operating the flow handling systems, predicting their reliability and useful life. This research explores the capacity of ultrasound particle image velocimetry (UPIV) for determining the impact parameters of solid particles projected from turbulent slurry onto a target surface. A slurry pot configuration was employed, and it was equipped with two linear transducers observing the flow at radial and axial planes. Three levels of rotational velocity were tested corresponding to the linear velocity of the moving target of 2.5, 3.0, and 3.5 m/s. For validation, the velocities and angles of individual particle impacts measured by UPIV were analyzed comparatively with analogous information derived by inverse analysis of effective wear scars using two deformation models. Velocity components measured by the two methods are statistically consistent for the two observation planes. The UPIV is concluded to present a new tool for the study of erosive wear with a focus on the slurry-target interface.

超声流动显示技术在紊流浆料中固体颗粒抛射侵蚀磨损研究中的适用性

研究浆料湍流引起的冲蚀对于设计和操作流处理系统，预测其可靠性和使用寿命至关重要。本研究探讨了超声颗粒图像测速（UPIV）在确定固体颗粒从湍流浆体投射到目标表面的冲击参数方面的能力。采用泥浆罐结构，安装了两个线性换能器，在径向面和轴向面观察流动。根据运动目标的线速度分别为2.5、3.0和3.5 m/s，测试了三个水平的旋转速度。为了验证，将UPIV测量的单个颗粒撞击速度和角度与使用两种变形模型的有效磨损痕反分析得出的类似信息进行了对比分析。两种方法测得的速度分量在两个观测平面上具有统计学上的一致性。UPIV为研究浆料-靶界面的侵蚀磨损提供了一种新的工具。

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
