Basically , the predicted cavitation phenomena coincides with those observed in the experiment for a corresponding model turbine , it indicates that the simulation can provide reference for the cavitation performance prediction of other turbines 数值预测的空化流动现象与模型水轮机空化试验中所观察到的现象基本一致，说明数值模拟结果可为水轮机的空化性能预测提供参考。
Further , the moving track of the cavity and its changing regularity of radius can be get along ~ vith the transformation of the pressure . in the calculation of this paper , matlab programming language is applied . in the past , fortran language is mostly used in scientific computation 空化现象与流场内的压力分布密切相关，根据压力的分布可以得到流场内的空化数分布，而空化数的分布决定了流场内的空蚀空化。
