Abstract

Numerical and aeroacoustic analyses are carried out on the emission of a propagating compression wave from an open end of a tube with an infinite baffle plate at the end. In the numerical analysis, the axisymmetric unsteady conservation equations are solved by a TVD scheme. A sample calculation shows that a rarefaction wave is reflected inward and an impulsive wave is generated and radiated outward from the open end. In the aeroacoustic analysis, a method of open - end correction is proposed. The magnitude of a generated impulsive wave and its attenuation with distance obtained by the numerical calculations are compared and discussed with the results by the aeroacoustic analysis with the proposed open - end correction.
