分离的产生将严重影响水力机械的流动特性，流动分离与水力损失密切相关。为了在设计中确定流动分离损失，该文通过利用死水区假设近似计算分离区的大小，提出了一种近似计算分离损失的方法。同时，给出了一种利用进出口参数来确定转轮内部流动分离的分离尺度和起始位置的工程模型。研究结果表明，流动发生分离后，在流向下游的过程中分离区不断扩大。流动分离的起始位置对转轮出口的分离尺度及水力损失有很大的影响。图５参５
The separation will seriously affect the flow characteristics of hydraulic machinery, and the flow separation is closely related to the hydraulic loss. In order to determine the flow separation loss in the design, this paper proposes a method of approximate calculation of the separation loss by using the assumption of stagnant water area to approximate the size of the separation zone. At the same time, an engineering model that uses the import and export parameters to determine the separation scale and starting position of the flow separation inside the runner is given. The results show that, after the separation of flow, the separation zone expands continuously in the process of flowing downstream. The starting position of flow separation has a great influence on the separation scale and hydraulic loss at the exit of the runner. Figure 5 reference 5
