Shock Wave Attenuation by Perforated Plates with Various Hole Sizes.

摘要

Results are presented for a set of experiments designed to determine the attenuation of shock waves passing through perforated plates as a function of peak overpressure and hole size for a given percentage of plate area vented. The venting hole size was varied from 1/8 inch (0.32 cm) to 2-13/16 inches (7.14 cm) as the vented area was varied from 5-50 percent open. The perforated plates were exposed to shock waves in a 4-inch (10.2 cm) shock tube over a range of peak shock overpressures from 200 psi (1379 kPa) down to 48 psi (331 kPa). (Author)
