The 3d cavitationflow field in the turbine runner and 3d cavity region onthe blade are predicted by the numerical simulation firstly.
通过数值模拟首次实现了混流式水轮机转轮内王维空化流场和叶片上三维空穴区域的预测。

Aiming at the high vaporous pressure and easy cavitation occurrence of water, the cavitationflow in orifices using water as working media is analysed theoretically by applying cavitation model.
In the process conditions permit, the change in pump flow, head, speed and medium operating temperature operating parameters, to avoid the occurrence of cavitation.
