颗粒冲击材料现象广泛存在于自然界以及工业领域中。应用实验测量与数值计算相结合的方法研究了颗粒射流冲击材料(304不锈钢)的磨损行为。考虑了颗粒粒; 径、运动轨迹、颗粒-壁面撞击点分布以及所导致材料物相结构变化。实验测试包括材料质量损耗、材料元素X射线衍射(XRD)分析、表面微观结构扫描电镜(; SEM)观察。对相应的颗粒射流冲击材料行为进行了数值计算,获得流场,颗粒场以及相应材料磨损。结果表明:颗粒射流冲击下颗粒运动轨迹与撞击点的分布不; 同,造成了材料样品表面磨损区域明显不同。颗粒-壁面碰撞不仅会导致材料损失而且会造成材料物相结构的变化。
Abstract
Particle-material impact is popular in the nature and industries. In; this work, experimental measurement and numerical calculation were; carried out to investigate the particle impinging jet effect on the; behaviour of material (304 stainless steel). Herein, particle diameter,; particle tracking trajectories, particle-wall collision point; distribution were considered to study material loss and the phase change; of material structure. In the experimental work, the measurements were; carried out for material mass loss, material element X-ray; diffractometry (XRD) analysis, surface micro-structure scanning electron; microscopy (SEM) observation and so on. In addition, the behaviour of; particle impinging jet impact on wall material was studied by numerical; simulations. Particularly, flow fields, particle trajectories and wall; material loss were obtained. The results show that particle collision; point distribution is quite different from their tracking trajectories; under particle impinging jet impact, which causes the wear zones on; sample surface different from each other obviously. It is concluded that; particle-wall impact will not only lead to material loss but also cause; the phase change of material structure.
