摘要
This paper concentrated on the effect of azimuthal variation of section shape on the instability of a cylindrical jet. A single fluid model under certain assumptions was constructed. The characteristic relation between frequency and wave number is obtained using the normal mode method. The effect of some parameters on the stability was examined and some phenomena in experiments were explained.
