Simulation of Hydrogen Explosions in Closed or Vented Connected Vessels

Résumé

The aim of this study was to characterize the interaction of a shock wave with a parallelepipedal obstacle. Shock wave properties were quantified downstream of sixty configurations with different obstacle dimensions. With the introduction of new parameters, these experimental measurements were used to write evolution laws for the arrival time and the maximum overpressure downstream of a parallelepipedal obstacle. The accuracy of these laws was satisfactory. Then, the maximum overpressure law was compared with experimental measures from the literature. Despite differences in the obstacle geometry or experimental setup, these experimental data are in good agreement with the maximum overpressure law.
