“…Even if the shockwave energy induced by a laser breakdown is at least two orders lower than that of an exploding wire, the time of deposit is such that powers (W•m −1 ) are the same order. As the initiation of direct gaseous detonation is due to the coupling energy/power in the cylindrical case [35], the laser source is a potential candidate to replace the exploding wire in risk study [36]. The potential benefits are in terms of safety (the ignition device is outside the gaseous charge) and energy control to generate both gaseous deflagrations and detonations.…”

The spatio-temporal evolution of the shock wave generated by a laser induced breakdown is often investigated and interpreted in the framework of the theory of shock similarity solutions. This work is a discussion about the choice of the most relevant geometry (spherical or cylindrical) to be used in the Jones modelling to track the intermediate-strength shockwave trajectory coming from a laser-induced non resonant breakdown in argon. Laser incident energies ranging from 10 to 200 mJwith initial pressure of argon from 250 to 2500 mbar are investigated using a Q-switched Nd:YAG laser operating at a wavelength of 532 nm with a 6 ns pulse duration. Experimental results show that using the radial component rb of the ellipsoidal shape of the shockwave with a cylindrical geometry best describes the shockwave trajectory over time. Moreover, the deduced characteristic length r0 allows to observe a shockwave shape similarity for all tested laser energies at a given pressure.

“…However, hardly any progress has been made in understanding the dynamic response of liquid storage tanks under blast loading [11]. A review of the literature shows that several researchers [6,[12][13][14] have investigated the influence of blast intensity, tank fill conditions, and tank bottom constraints on tanks' failure mode, resultant displacement and deformation, structural energy, circumferential strain, and longitudinal strain. Moreover, small-scale model experiments have been mostly conducted to study the response of thin-wall cylindrical tanks subjected to blast load [3,6], and the findings have been verified using numerical simulations.…”

Thin-Walled Cylindrical Shell Storage Tank under Blast Impacts: Finite Element Analysis

et al. 2021

Thin-walled cylindrical shell storage tanks are pressure vessels in which the walls of the vessel have a thickness that is much smaller than the overall size of the vessel. These types of structures have global applications in various industries, including oil refineries and petrochemical plants. However, these storage tanks are vulnerable to fire and explosions. Therefore, a parametric study using numerical simulation was carried out, considering the internal liquid level, wall thickness, material yield strength, constraint conditions, and blast intensity, with a diameter of 100 m and height of 22.5 m under different blast loads using the finite element analysis method. The thickness of the tank wall is varied as 10 mm, 20 mm, 30 mm, and 40 mm, while the fill level of internal fluid is varied as 25, 50, 75, and 100%. The blast simulation was conducted using LS-DYNA software. The numerical results are then compared with analytical results. The effects of blast intensity, standoff distance, wall thickness, and fill level of internal fluid on the structural behaviour of the storage tank were investigated and discussed.
