The studies of characteristics and load configuration of an electromagnetically driven shaped liner during the collapse process are significant for understanding its physical process deeply and guiding its application. A coupled electromagnetic-mechanical–thermal physical model was established and validated for characterizing electromagnetically driven shaped liners. The parameters of the liner st...Show More
Explosive-driven magnetic flux generator is one of the most efficient techniques for producing ultrahigh magnetic fields in a relatively large volume. To create a more reliable system suitable for extreme magnetic fields applications, a compact explosive-driven magnetic flux compression system with a small amount of explosive for generating multimegagauss fields was developed. In this paper, the d...Show More
The ElectroMagnetic Flux Compression (EMFC) has important applications in solid-state physics (ultrahigh magnetic field physics, high pressure science), and is also likely to find applications in fusion and high-energy density researches. In the Institute of Fluid Physics (IFP), Chinese Academy of Engineering Physics (CAEP), a mediumsized EMFC device has being developed to carry out some extreme p...Show More
Based on the 1-D elastic-plastic reactive hydrodynamic code Simplified Stretch Sin, a magnetohydrodynamic (MHD) version SSS/MHD has been developed. The new code is of multifield coupling, making use of the Resistance-Inductance-Capacitance circuit equations related to loading currents and others. To calculate MHD and circuit variables consistently and simultaneously, on the basis of Faraday's law,...Show More
Numerical simulations of metallic foil electrically exploding provide the feasibility to analyze the process better and then to suggest new ideas to optimize the design of experiments and some other applications. Incorporating with a tabular equation of state and Burgess resistivity model in which multiphases are covered and a unified set of modified resistivity coefficients for aluminum (or coppe...Show More
The cylindrical isentropic compression by high magnetic field pressure is very useful in high energy density physics. Some primary experimental works on the explosively magnetic flux compression generator had been carried out since 2011 at Institute of Fluid Physics, Chinese Academy of Engineering Physics (IFP, CAEP). A traditional configuration of explosively driven flux generator had been design...Show More
