Abstract

Abstract

A high-pressure-gas-driving blast wave simulation shock tube, commonly composed of driving section, throat section and expansion section, is an ideal platform for explosion damage effect research of long positive shock pressure duration time in the laboratory, as the ability of generating simulated shock wave with similar characteristics to real explosion wave. One of the core problems in the design of blast simulation shock tubes, is the control method of the simulated wave attenuation process by modifying the variable section structure and the driving section shape of the shock tube. In this article, a numerical calculation model of one-dimensional flow in the shock tube is established based on the explosion simulation shock tube in the laboratory, a similarity evaluation method of simulated shock wave and standard explosion wave in a shock tube based on determination coefficient is proposed referring to the statistical theory. Then, based on the flow characteristics of the variable section shock tube, the influence of the shape of the driving section on the shock wave attenuation history is studied. The results show that, it is feasible to acquire simulated wave with approximate exponential attenuation history of real blast wave, by using variable cross-section driving tube, of which the section diameter decreases with the growth of distance to the throat, optimizing the variable cross-section structure due to the determination coefficient, and controlling the motion property of expansion and compression wave in the shock tube.
