内容記述 | Axisymmetric underexpanded supersonic jets are investigated numerically. A time-depended technique of solution is applied to solve the Euler equations for a compressible ideal gas. The characteristics of Mach disk obtained by the calculations are compared with the experiments and a good agreement is obtained. It is shown that the global jet structure with a nearly regular shock pattern which is stable and steady itself, is destabilized by the vortex rings (Kelvin-Helmholtz roll-up) on the jet boundary. These vortices produce shocks inside the jet, which are convected downstream with eddies. This strongly suggests that a time-independent or a time-con-verged solution cannot be expected without making a suitable time-averaging of the time-dependent solutions. Other important instabilities are also investigated. | |||||
