混流式水轮机转轮端面空化探讨

Discussion on end-surface cavitation of Francis runner

本文介绍了混流式水轮机转轮出现的端面空化,探讨了水轮机转轮出现端面空化的原因,对防范模型试验中此类空化的发生提出了建议。并简单探讨了此类空化模型水轮机与真机的相似性。

This paper describes the end-surface cavitation of a Francis runner, analyzes the cause for this type of cavitation, and suggests some precautions. A brief discussion on the similarity between prototype and model turbines is given.
