Numerical Study on the Shock Wave Scattering Phenomenon Behind a Finite Wedge
- 발행 : 1999.05.01
초록
The shock wave diffracted behind a finite wedge is partially scattered after interacting with a starting vortex originated from the sharp vertex of the wedge. The shock is divided into the accelerated and decelerated shocks. The decelerated shock then interacts with the small vortexlets brought about by the vortex instability, producing weak compression waves. The shock-shock interaction produces Mach stems. Through this successive process, the shock attenuated. In this study, these complicated shock phenomena are computed using Euler equations and compared with experimental results obtained by the authors.
