“…The experiments were carried out in the large-scale Shock Tube Research Facility of the Department of Mechanical Engineering at CCNY. The facility is shown schematically in figure 4 and is described in detail by Briassulis, et al (1998) [21]. It has been used extensively for research on shock wave interactions with turbulence and vortices (Andreopoulos et al, 2000;Briassulis et al, 2001, Agui et al, 2005 [22][23][24] and shock interactions with monolithic and composite plates Gong & Andreopoulos (2008) [16].…”

“…Thus, the change of momentum leads to (20) or (21) It is very tempting to form the change of momentum between the incoming flow behind the incident shock and the outgoing flow with the reflected shock after the impact of the shock on the plate. However, the two expressions (18) and (21) are relatively to the moving shocks which propagate with different speeds and . The two reference velocities do not cancel each other and therefore the momentum difference here is not Galilean invariant.…”

An experimental investigation was carried out to consider the partitioning of energy deposited by a planar shock impinging on thin metallic plates mounted at the end wall of a large scale shock tube. A split-view time-dependent digital image correlation technique was employed to capture the threedimensional motion of the external surface of the specimens. Steel plate and aluminum plates were tested in the present work. The experimental results were analyzed by using the control volume approach with moving boundaries and the presence of discontinuities. The energy deposition by the flow on the specimens were examined and discussed in two different frames of reference to demonstrate that energy is not Galilean invariant. It was found that most of the deposited energy is spent on plastic deformation of the plates followed by the kinetic energy, which reached significant values only in the initial stages of the shock-material interaction.

The unsteady interaction of a moving shock wave with nearly homogeneous and isotropic decaying compressible turbulence has been studied experimentally in a large-scale shock-tube facility by using rectangular grids of various sizes. The interaction has been investigated by measuring velocity, total pressure, and temperature inside the ow eld and static pressure at the wall of the shock tube with instrumentation of temporal and spatial resolution. Attenuation of the shock wave strength has been found to take place as a result of the interaction with the turbulent ow eld, which depends on the mesh size of the grid or its Reynolds number, the ow Mach number, and the initial Mach number of the shock wave. Finer grids produce turbulence, which attenuates the shock wave more than coarse grids at the same Mach number. Ampli cation of pressure uctuations after the interaction has been observed in all experiments, depending on grid size (initial turbulence level) and shock strength. Furthermore, this ampli cation is not the same through the whole range of wave numbers resolved.

“…Aso et al (2005) used a shock tunnel to investigate the supersonic combustion phenomena and observed that the reflected shock wave heated the air to a stagnation temperature of 2800 K and the static temperature of the test section was 1550 K. This temperature is sufficient to generate the supersonic combustion with self-ignition. In addition, there have been many different methods used to develop and improve the performance of high speed fluid flow test facilities and to obtain higher values of shock Mach number (Briassulis et al, 1996;. Lu et al (2009) developed a new technique to improve the performance of these facilities.…”

This paper presents an experimental investigation into the effects of area contraction on shock wave strength and peak pressure in a shock tube. The shock tube is an important component of the short duration, high speed fluid flow test facility, available at the Universiti Tenaga Nasional (UNITEN), Malaysia. The area contraction was facilitated by positioning a bush adjacent to the primary diaphragm section, which separates the driver and driven sections. Experimental measurements were performed with and without the presence of the bush, at various diaphragm pressure ratios, which is the ratio of air pressure between the driver (high pressure) and driven (low pressure) sections. The instantaneous static pressure variations were measured at two locations close to the driven tube end wall, using high sensitivity pressure sensors, which allow the shock wave strength, shock wave speed and peak pressure to be analysed. The results reveal that the area contraction significantly reduces the shock wave strength, shock wave speed and peak pressure. At a diaphragm pressure ratio of 10, the shock wave strength decreases by 18%, the peak pressure decreases by 30% and the shock wave speed decreases by 8%.
