“…A, B and C in Figure 9 are results of 1kg TNT at the explosion distance of 1, 14 and 35m. Figure 9D and Figure 10 which is from literature [11], we can find that the overpressure time distribution are consistent. …”

This paper presents a new engineering model on the air blast wave of TNT explosive. The model is built and the parameters are calibrated based on numerical simulated pressure time data of shock wave in air. The model describes the peak overpressure, impulse, typical time and attenuation coefficient of the shock wave with new computational equations. Comparison of pressure configuration for the scaled distance shows that the present engineering model can give consistent results with the numerical code and experiments.

“…Figure 2B is relative error of fitted data for overpressure and it shows the maximum error is about 7%. Figure 3 is the comparison of the peak overpressure between the present model and the previous engineering equations [2][3][4][5][6][7] and some experiments in literature [11,12].…”

“…These shear rates and frequencies remain lower, however, than what is achieved in many industrial applications, such as the mitigation of shock and blast waves by aqueous foams (Goldfarb et al, 1997, Britan, Liverts & Ben-Dor, 2009, Del Prete et al, 2013, or the design of new probes of liquid foams based on their acoustic response. A related subject is the propagation of acoustic waves through foams, which has been surprisingly considered only rather recently (Moxon, Torrance & Richardson, 1988, Mujica & Fauve, 2002, Kann, 2005, Pierre et al, 2013, Pierre, Dollet & Leroy, 2014.…”

Coupled vibrations of a meniscus and liquid films

We investigate the vibration properties of a circular horizontal film that is bounded by a meniscus (or Plateau border) and suspended between two catenary films. The suspending films act as capillary springs, and the system is thus free to oscillate around its equilibrium position. We study its free and forced oscillations. In our experiments, we track simultaneously the positions of the Plateau border and the film. The model that we present predicts the eigenfrequency of the system and its resonance characteristics (in forced oscillations). In particular, we show that the dynamics of both the Plateau border and the film have to be taken into account in order to provide an accurate prediction of the oscillation frequency.

“…The modeling aspect of blast/shock waves mitigation was also discussed. The paper presented by Del-Prete et al [34] describes experimental and numerical investigations on the mitigation of blast waves using dry aqueous foams. Different tests were conducted in sub-and full-scale configurations using three different masses of explosive.…”
