流体在环形狭缝中流动时园柱体的微振动

The Microvibration of a Streaming Fluid within an Annular Gap Formed by Two Concentric Cylinders

本文讨论了在两个园柱体的环形狭缝中不可压缩流体的流动．在一定的假设下，运用流体力学方程和流体对柱体的作用方程，导出了附加质量和转动惯量、振动频率和衰减系数．并对文（１）中的某些结果进行了必要的修正．

In this paper, the flow of incompressible fluid within an annular gap formed by two cylinder was studied.Based on some approximation, the additional mass, moment of inertia, frequency of vibration and damping. coefficient are derived from the fluid mechanical equation and fluid-structure -interaction equation.At last, some results in the paper [1] are revised.
