Electrical Characteristics of Underwater Wire Explosion Influenced by Wire Parameters

Strategic Insights

— 2 min read

Researchers at Huazhong University of Science and Technology have conducted a comprehensive study on the effects of wire parameters on the electrical and shock wave characteristics during the underwater electrical wire explosion (UEWE) process. According to the study, the parameters of the wire and circuit significantly influence the discharge characteristics and shock wave behavior. The research team established a numerical model that describes the UEWE process and a derived finite element model. Funders for this research include Xiaotao Han, National Natural Science Foundation of China (NSFC), and Key R&D Project of Hubei Province.

Key Takeaways:

  • The parameters of the wire and circuit significantly influence the discharge characteristics and shock wave behavior during the UEWE process.
  • Shorter and thinner wires, as well as faster discharge frequencies, promote quicker energy deposition, resulting in higher discharge channel (DC) pressure peaks.
  • The amplitude of the shock wave is closely correlated with the DC pressure peak and its attenuation characteristics.
  • To achieve a higher shock wave amplitude, thin and short wires should be chosen for the near-field water region, while long and thick wires should be selected for the far-field water region.
  • Reducing the wire diameter can minimize pressure attenuation within a certain range of inductance variations.
  • The model can be integrated with neural networks for multi-objective optimization, enabling the determination of the optimal parameter combination for a given operating condition.
  • Xiaotao Han and research team developed a numerical model that describes the UEWE process and a derived finite element model.
  • The research team analyzed the impacts of wire and circuit parameters on the physical characteristics, electrical properties, and shock wave characteristics during the UEWE process.

Statistics:

  • 138th volume of Journal of Applied Physics published in 2025 contains the research article on the effects of different parameters on the electrical and shock wave characteristics in underwater electrical explosion of copper wires.
  • The amplitude of the shock wave increases with higher discharge channel (DC) pressure peaks, which are promoted by shorter and thinner wires.
  • The effect of capacitance on shock wave amplitude is minimal within a certain range of wire diameters.
  • Inductance significantly influences the shock wave amplitude, but reducing wire diameter can minimize pressure attenuation within a certain range of inductance variations.
  • The researchers conducted a comprehensive study on the effects of wire parameters on the electrical and shock wave characteristics during the UEWE process.
