摘要：

The study of oscillatory instabilities occuring in cryogenic systems has a practical importance in the system development. One form of instability, thermally driven acoustic oscillation, is investigated experimentally using U-shaped tubes. The stability limit of oscillation for helium gas predicted by theory agrees well with our experimental results. The temperature ratio of a warm part to a cold one and the ratio of the inner radius of the tube to the Stokes boundary layer thickness are convenient variables for characterizing thermally driven acoustic oscillation. © 1979.
