气核尺度对空化现象的影响

Influences of Gas Nucleus Scale on Cavitation

本文计算了不同尺度的气核对空化现象的影响.结果表明,不同尺度的气核具有不同的空化起始条件及不同的发育和溃灭过程.在计算、模拟空化现象时应当考虑到这一因素.

The influences of gas nucleus scale on cavitation are analysied in this paper. The results show that there are different inception conditions growth and collapse processes of bubble for the gas nucleus with different scale. The influences shoud be considered in calculating and simulating cavitation.
