OVERPRESSURES AND DURATIONS OF SHOCK WAVES EMERGING FROM OPEN-ENDED SHOCK TUBES
Abstract
The field wave overpressures and durations resulting from shock waves emerging from open-ended shock tubes have been measured. An equation has been developed from the measured data that relates the field overpressures (below 0.1 psi) resulting from a given shock tube pressure, to the tube diameter and distance from the tube exit. An equation has also been developed from the same data that relates the duration of the field wave (below 0.1 psi) to the exit areas of the tubes for a given shock tube pressure. Predictions of field overpressure and duration have been made for an eight foot diameter shock tube firing a 27 psi shock wave.
