This study aims to investigate the aluminum (Al) arc plasma parameters generated through the explosive strip technique. The research involves the measurement of key plasma characteristics such as plasma frequency (fp), Debye length, and Debye number. The electron temperature (Te) and electron density (ne) of the plasma were calculated utilizing the Boltzmann plot and Stark expansion method. Analysis of the optical emission spectrum revealed distinctive peaks corresponding to oxygen, Al, and zinc oxide (ZnO) within the plasma. The outcomes of the study demonstrated a noteworthy correlation between the applied current and the electron temperature and density. Specifically, as the current increases, both electron temperature and density increase. The electron temperature of the Al plasma increased from the range of 0.852 eV to 0.92404 eV, accompanied by a corresponding elevation in electron density from 13.1× 1017 cm-3 to 15.2× 1017 cm-3. Furthermore, the detonation of the Al strip within a ZnO suspension led to even more pronounced changes. In this case, the electron temperature surged from 0.92885 eV to 1.1012 eV, and the electron density experienced an increase from 37.7 × 1017 cm-3 to 44.7 × 1017 cm-3.

“…Comparatively, electrical wire explosion technology has several advantages, including controllable load, high energy conversion efficiency, stronger shock waves, and high repeatability [12]. In addition, the strength of the shock waves can be further enhanced by detonating energetic materials through electrical wire explosion [13][14][15]. Therefore, this paper mainly investigates the pile expansion effect achieved by the shock waves of electrical wire explosion in liquids.…”

Compaction of the soil around the borehole filled with cement paste can build shaped pile foundations, effectively increase enhancing the bearing capacity of the pile foundations. Shock waves of electrical wire explosion in liquids can compact the soil and build expanded pile foundations, which has broad industrial application prospects. Electrical wire explosion in liquids has the advantages of high efficiency, good repeatability and controllability. In order to analyze the mechanism of pile expansion by electrical wire explosion in liquids, in this paper, a comprehensive test platform for pile expansion by electrical wire explosion was established, the voltage and current of the discharge channel were measured. The expanded piles were built through multiple discharges, and the size and bearing capacity of the piles were measured. Based on the finite element numerical method, a three-dimensional model of soil compaction by shock waves was established, and the material parameters, model dimensions were reasonably determined. The propagation and attenuation processes of shock waves in cement paste and soil were simulated, and the soil compaction process was obtained. The cumulative effect of pile expansion under multiple shock wave actions was analyzed and compared with test results.

Underwater electrical wire explosion (UEWE) is an efficient source of underwater shock waves (SWs). In order to efficiently simulate the interaction between the UEWE SW and structures, a coupled model that includes the electric circuit, the exploding wire and the surrounding water is established based on user-subroutines provided by the commercial explicit dynamics software ANSYS AUTODYN. The modeling starts from room temperature by using the tabular wide-range metal equation of state (EOS) and conductivity data. Experimental validation is performed with copper wires exploded by a μs-timescale pulsed discharge. The numerical results show satisfactory consistency with experiments in terms of the current and voltage waveforms, the wire expansion trajectory, the evolution of SW front, the interaction between SW and electrodes and the SW pressure profiles. The main discrepancy lies in the SW amplitude that is ~20% higher in the calculation and the possible reasons are discussed in detail. Based on this approach and with proper modifications to the metal EOS and conductivity data, the interaction between UEWE SWs and structures can be efficiently modeled in 2D and 3D for practical applications.
