Highlights

?Perforated plates arrays impinged by a shock wave were experimentally studied.

?Array size, plate geometry, blockage ratio and type of gas were varied.

?The pressure buildup was found to depend on a gas-specific parameter.

?A macroscopic methodology was used to study the effects of the plates array.

?All the results were found to have a similar non-dimensional form.

Abstract

The pressure buildup behind an array of perforated plates following a shock wave impingement was experimentally studied. The experiments were performed in a shock tube facility and the arrays were varied in the number of their perforated plates and the porosities of the plates. It was found that the pressure buildup behind all of the configurations that were examined displayed similar characteristics. Using simplified assumptions about th
