离心轮内轴向旋涡流线谱是在利用薄膜变形与旋涡运动相似的条件下首次被实验确定的尽管在这种情况下使用的实验设备结构简单,但为了保证压紧或粘贴在被研究断面轮廓线上的橡胶薄膜之起始张力恒定不变,是有相当大的困难。橡胶薄膜的起始张力若非恒定不变,则将破坏接收液流图象的模拟并使得由轴向旋涡引起的旋涡运动的形态失真。在某些情况下用肥皂膜代替橡胶膜片。然而安排这样的实验是与缩小叶片间流道模型相联系的
The axial vortex flow profile in the centrifugal wheel was first experimentally determined using similar film deformation and vortex motion. Although the experimental equipment used in this case was of a simple structure, in order to ensure the compactness or sticking of the film in the studied section The initial tension of the rubber film on the contour line is constant and there is considerable difficulty. If the initial tension of the rubber film is not constant, the simulation of the received flow image will be broken and the morphology of the vortex motions caused by the axial vortices will be distorted. In some cases replace the rubber diaphragm with soap film. However, arranging such an experiment is associated with reducing the flow path between the leaves
