| Abstract: | The stability of an inviscid compressible swirling flow between two concentric cylinders is analytically investigated. Two stability criteria are derived for compressible swirling flows under narrow gap approximation by an analytic method analogous to Ludwieg's method. Finally, the effect of compressibility is discussed. |
