Abstract: We use a simple, collision-based, discrete, random abrasion model to compute the profiles for the stoss faces in a bedrock abrasion process. The model is the discrete equivalent of the gener...
含沙水流中翼型空蚀磨损试验（Experiment on Damage of Cavitation and Silt Abrasion for Hydrofoil in Silt-laden Water Flow）
翼型 含沙水流 空蚀 磨损
2010/12/29
模拟水力机械内部流动环境，在收缩－扩散型试验段中对翼型进行了空蚀、磨损及两者联合作用破坏试验，观测表面破坏微观形貌并测量破坏深度分布规律。空蚀形貌呈较为规则的近圆独立蚀坑，其分布较为随机。根据颗粒对表面作用的不同，磨损形貌表现为冲击、铲削、犁耕及切削等类型。在较高固相质量浓度下，联合作用破坏形貌大多在极端的角度(90°或0°)以颗粒磨损形式出现，其尺度特征在翼型表面随位置后移远大于磨损形貌，宏观破...
