A METHOD FOR PREDICTING BLAST WAVE OVERPRESSURE PRODUCED BY RUPTURE OF A GAS STORAGE VESSEL

摘要

A METHOD, BASED ON A HYDRODYNAMIC SOLUTION TO THE SPHERICAL SHOCK PROBLEM, IS DEVELOPED TO PREDICT BLAST WAVE OVERPRESSURE. GENERALIZED CURVES ARE PRESENTED THAT PERMIT THE APPLICATION OF THIS TECHNIQUE TO A WIDE RANGE OF PRESSURE VESSEL SIZES AND PRESSURES. SAFETY ANALYSES OF HIGH PRESSURE SYSTEM FAILURES ARE NORMALLY BASED ON SCALED EXPLOSIVE DATA (TNT SCALING). AN EVALUATION OF AVAILABLE EXPERIMENTAL DATA INDICATES THAT THE HYDRODYNAMIC MODEL PROVIDES A BETTER APPROXIMATION OF BLAST OVERPRESSURES GENERATED WHEN A PRESSURE VESSEL RUPTURES.
