1973年在列宁格勒举行了题为《室内侵蚀试验进行的方法、气蚀和空穴的侵蚀作用强度的估计》的讨论会。室内试验及原型戏测证明:当保持运动相似和空穴数相等时,气蚀作用的部位是很相似的(1、2、3),在空穴刚开始时,在模型和原型上所得之临界空穴数也很一致④。但是,除以上参数外,空蚀作用强度还与绕流的绝对流速和物体的尺寸有关。因此,建议应尽量在接近原型流 A seminar titled “Methodology for Indoor Erosion Testing, Estimation of Cavitation Erosion and Cavitation Erosion Intensity,” was held in Leningrad in 1973. Laboratory tests and prototype tests show that the cavitation sites are similar (1, 2, 3) when the motions are similar and the number of cavities are equal. At the very beginning of cavitation, the resulting model and prototype Critical hole number is also very consistent ④. However, in addition to the above parameters, the cavitation erosion intensity is also related to the absolute velocity of flow around the object and the size of the object. Therefore, suggestions should be as close as possible to the prototype flow
