“…The Mach number of the shock wave also increased in the shock tube when the pressure ratio across the diaphragm was increased. After the incident shock reached the end wall of the shock tube, the reflected shock traveled back into the oncoming gases because it is stopped by the end wall of the shock tube (9, 10). …”

The transformation of a time-dependent pressure pulse imposed on the front face of a rigid porous medium sample, mounted in a tunnel, through the sample and a fixed-volume air gap between the rear face of the sample and the end wall of a tunnel is studied both experimentally and analytically. In the experiments, rigid porous samples that are placed at various distances from a shock tube end wall are subjected to the impingement of shock waves. The pressure buildup behind the porous sample is monitored and compared with the pressure imposed at the front face of the porous sample. The shock tube is fitted with a short driver section in order to generate blast-like decaying pressure profiles, which continue to decay after the initial shock impingement. In this scenario, the measured pressure profile at the end wall, which is affected by the properties of the porous medium and the size of the air gap separating its rear face and the shock tube end wall, is significantly different from the pressure profile imposed on the front face of the porous sample. The mechanism governing the pressure transformation provided by the porous medium is attributed to a selective filtration process that attenuates the pressure changes associated with high frequencies. The results of the present study are also analysed in conjunction with previously published analytical and numerical models to achieve a broader understanding of the physical mechanisms affecting the pressure buildup.

“…For physical simulation of the high-explosive blast impact on a target (protected) object in Russia [1][2][3][4] and abroad [5][6][7][8][9][10][11], shock tubes are traditionally used. The advantages of this method of physical simulation over full-scale field tests are lower cost and easier reproducibility of the experiment, as well as its higher safety.…”

“…The problems of constructing shock tubes with a given pressure profile of the resulting waves were previously solved numerically and analytically [3,12,13]. The increased attention paid nowadays to testing various means of explosion protection makes it necessary to consider this issue in more detail.…”

The problem of generating pressure waves with a profile similar to the profile of a blast wave in closed shock tubes with constant cross-section is considered. Applying non-stationary gas dynamics methods, the dimensions (lengths) of high and low pressure chambers are determined analytically and numerically. Also, the gas parameters in those chambers necessary to produce pressure waves with a profile close to triangular are determined.
