Study on the Characteristics of Impulse Wave Discharged from the Tube Exit with Non-Circular Cross-Section
비원형 관출구로부터 방출되는 펄스파의 특성에 관한 연구
- Published : 2003.11.05
Abstract
When a shock wave arrives at an open end of tube, an impulse wave is discharged from the tube exit and complicated flow is formed near tube exit. The flow field is influenced by the cross-sectional geometry of tube exit, such as circular, square, rectangular, trapezoid and etc. In the current study, three-dimensional propagation characteristics of impulse wave discharged from the tube exit with non-circular cross section are numerically investigated using a CFD method. Total variation diminishing (TVD) scheme is used to solve the three-dimensional, unsteady, compressible Euler equations. Computations are performed for the Mach numbers of the incident shock wave
