| Abstract: | The Ludwieg criterion on stability of incompressible inviscid swirling flow is extended to the compressible flow. From the analysis of physics mechanism about flow. A stability criterion about compressible inviscid swirling flow under difinited directed disturbances is derived. This criterion is compared with other stability condition. |
