When the pulsating pressure wave propagated in the tube reaches at open end of tube, the reflection and emission of pressure wave occur and the multiple impulsive waves are formed. This multiple impulsive waves cause the some noise problems as like exhaust tube of automobile. It seems that the characteristics of multiple impulsive waves and the formation mechanism of multiple impulsive waves have to be more cleared to control the noise problem. This paper aims to clear the characteristic of multiple impulsive waves, the relation between the pulsating pressure wave and multiple impulsive waves. The numerical and experimental investigations were carried out using the TVD method.
