概要

• 論文の詳細を見る

• This paper deals with the vibration and the stability of a cylindrical shell conveying a compressible fluid taking into account an effect of the boundary layer of the fluid. Mizoguchi's shell theory is used and the compressible fluid is treated as an ideal gas. The frequencies of shell vibrations are obtained for several flow speeds ranging from 10m/sec to Mach 3 under two kinds of the mean static pressures of the fluid. From the results with the infinitely long pipeline the cases of periodical support may be obtained by means of some simple drawings as in the first author's previous paper. The instability is discussed based on an energy consideration of the shell and fluid.
