Interaction of unsteady pressure waves and perforated baffles

Interaction of unsteady pressure waves and perforated baffles

The results of experiments to investigate the interaction of plane shock waves with a triangular pressure profile and perforated baffles are presented. The parameters of the reflected waves are determined and the amplitude and impulse attenuation coefficients are measured as functions of the permeab...

Zusammenfassung:The results of experiments to investigate the interaction of plane shock waves with a triangular pressure profile and perforated baffles are presented. The parameters of the reflected waves are determined and the amplitude and impulse attenuation coefficients are measured as functions of the permeability of the barrier. The quenching coefficients are determined for the case of two baffles arranged in series.
