Paper Abstract

The load acting on the wall of a pipe by a throughgoing detonation is not yet well characterized. Reasons are the limited amount of data on sufficiently accurate pressure/time traces of the detonation peak and the requirement of considering the dynamics of the system instead of just doing a static approach. To determine the dynamic response of the pipe wall on a detonation we performed laser velocimetric measurements and compared the results to theoretical calculations. There is good agreement between measured and predicted values of vibration frequencies, amplitudes and vibration velocities. Furthermore it was found that various radial vibration modes other than the fundamental one ((phi) -symmetry) are excited. This must be attributed to the complex structure of the detonation front which is not just a plane of high pressure oriented vertical to the axis of the pipe.
