When a compression wave propagates along a constant-area straight tube and reaches its open end, an impulsive wave is emitted outward from the exit toward the surrounding area. Assuming a compression waveform as an arctangent curve, the magnitude of an impulsive wave is obtained explicitly in terms of the pressure rise and length of the compression wave. The variation of pressure with time at the exit and the magnitude of an impulsive wave obtained from the present method agree well with the numerical results solved by the TVD scheme.
