The evolution characteristics of pressure pulse in the shock tube are studied to generate a shock wave similar to the air explosion shock wave in the tube. The process of forming a shock wave similar to air explosion shock wave in shock tube driven by high pressure gas is analyzed through the experimental study and numerical simulation of pressure pulse characteristics in shock tube
and the relationship between shock wave characteristics and shock tube parameters is established. The results show that the shock wave generated in the shock tube is a plane wave. When the length of the low pressure section of shock tube is long enough
the reflected rarefaction wave in the low pressure section can catch up with the right shock wave front
and form a shock wave similar to the air explosion shock wave at the overtaking position. The decrease in the driving pressure and length of the high pressure section makes the rarefaction wave easier catch up with the shock wave. As the pressure in the low pressure section increases
the velocity of the shock wave decreases
and the reflected rarefaction wave catches up with the shock wave faster. At the same time
the shock wave travels shorter in the low pressure section
and the positive pressure duration of the shock wave pressure is shorter. The characteristic parameters such as peak overpressure and positive pressure duration of shock wave are related to the driving pressure and length of the low pressure section of the shock tube. Combined with dimensional analysis
the minimum length of low pressure section required to form simulated air explosion shock wave is established
and the relationship among the characteristic parameters such as peak overpressure and positive pressure duration of shock wave and the parameters such as pressure and length in shock tube is established
which provides basic theory and data support for the design of simulated air explosion shock tube.

Neurobiology of disease , 2011 , 41 ( 2 ): 538 - 551 . DOI: 10.1016/j.nbd.2010.10.025 http://doi.org/10.1016/j.nbd.2010.10.025 Current experimental models of blast injuries used to study blast-induced neurotrauma (BINT) vary widely, which makes the comparison of the experimental results extremely challenging. Most of the blast injury models replicate the ideal Friedländer type of blast wave, without the capability to generate blast signatures with multiple shock fronts and refraction waves as seen in real-life conditions; this significantly reduces their clinical and military relevance. Here, we describe the pathophysiological consequences of graded blast injuries and BINT generated by a newly developed, highly controlled, and reproducible model using a modular, multi-chamber shock tube capable of tailoring pressure wave signatures and reproducing complex shock wave signatures seen in theater. While functional deficits due to blast exposure represent the principal health problem for today's warfighters, the majority of available blast models induces tissue destruction rather than mimic functional deficits. Thus, the main goal of our model is to reliably reproduce long-term neurological impairments caused by blast. Physiological parameters, functional (motor, cognitive, and behavioral) outcomes, and underlying molecular mechanisms involved in inflammation measured in the brain over the 30 day post-blast period showed this model is capable of reproducing major neurological changes of clinical BINT.Copyright © 2010 Elsevier Inc.

DOI: 10.1089/neu.2010.1513 http://doi.org/10.1089/neu.2010.1513 Blast-induced mild traumatic brain injury (bTBI) has become increasingly common in recent military conflicts. The mechanisms by which non-impact blast exposure results in bTBI are incompletely understood. Current small animal bTBI models predominantly utilize compressed air-driven membrane rupture as their blast wave source, while large animal models use chemical explosives. The pressure-time signature of each blast mode is unique, making it difficult to evaluate the contributions of the different components of the blast wave to bTBI when using a single blast source. We utilized a multi-mode shock tube, the McMillan blast device, capable of utilizing compressed air- and compressed helium-driven membrane rupture, and the explosives oxyhydrogen and cyclotrimethylenetrinitramine (RDX, the primary component of C-4 plastic explosives) as the driving source. At similar maximal blast overpressures, the positive pressure phase of compressed air-driven blasts was longer, and the positive impulse was greater, than those observed for shockwaves produced by other driving sources. Helium-driven shockwaves more closely resembled RDX blasts, but by displacing air created a hypoxic environment within the shock tube. Pressure-time traces from oxyhydrogen-driven shockwaves were very similar those produced by RDX, although they resulted in elevated carbon monoxide levels due to combustion of the polyethylene bag used to contain the gases within the shock tube prior to detonation. Rats exposed to compressed air-driven blasts had more pronounced vascular damage than those exposed to oxyhydrogen-driven blasts of the same peak overpressure, indicating that differences in blast wave characteristics other than peak overpressure may influence the extent of bTBI. Use of this multi-mode shock tube in small animal models will enable comparison of the extent of brain injury with the pressure-time signature produced using each blast mode, facilitating evaluation of the blast wave components contributing to bTBI.

The facility was found to generate a planar shock wave over the tube cross section by measuring the pressure distribution on a massive steel plate located at the end of the tube. The properties of the shock wave proved to be a function of driver length and driver pressure, and the positive phase of the measured pressure–time histories was similar to those generated from actual far-field explosive detonations. However, the shock tube is also suited to investigate fluid–structure interaction effects and the behaviour of materials in blast events. This was demonstrated using a three-dimensional digital image correlation technique to measure the deformation field of thin steel plates. Synchronization of the three-dimensional digital image correlation and pressure measurements enabled a thorough investigation of the entire experiment and identification of fluid–structure interaction effects. Finally, one-dimensional numerical simulations were performed to investigate the wave patterns during the experiments.
