Abstract

A flow of silicon fluid in the gap between eccentric cylinders was studied experimentally. The condition of gaseous cavitation inception during the rotation of internal cylinder was considered. It was shown that at reduction of the gap between cylinders Saffman–Taylor instability appeared on surface of the internal cylinder and then gaseous cavitation was observed. Possibility of one uniform gas formation appearance under this type of instability was demonstrated.

气体空化时偏心圆筒的Saffman-Taylor不稳定性

实验研究了硅流体在偏心圆筒间隙中的流动。考虑了内筒旋转过程中气体空化产生的条件。结果表明，当柱间间隙减小时，内柱表面出现了Saffman-Taylor不稳定性，并出现气穴现象。证明了在这种不稳定性下，有可能出现一种均匀的气体形成。
