【摘要】 模型水轮机空化状态的界定普遍依靠观测试验来实现,观测多采用人工观测的方法,也有采用摄像机摄像的方式进行试验,两种方式均存在各自的缺陷。本文根据观测试验原理提出一种同步成像方法并设计同步成像系统,成像系统的应用对模型水轮机水力性能优化设计及空化研究提供有力支持。更多还原

【Abstract】 The judgment of cavitation of model hydro-turbine mainly depends on observation, and the artificial way is usually chosen to achieve that. Observation with video camera is common, too. However, both artificial way and observation with video camera are defective. A synchronization imaging method is presented in this paper according to the principle of cavitation observation, and a synchronization imaging system is designed. The application of synchronization imaging system will be significant for optimization design of model hydro-turbine and research of cavitation.更多还原
