Influence of the Wire Spatial Structure on the Distribution of Product and the Peak Overpressure of Shockwave Generated by the Electric Explosion

The deposition energy and the peak overpressure of shockwaves are leading engineering parameters wire electric explosion technology applied to enhance oil recovery. thicker Cu deposits more energy, which transforms into shockwave efficiently. Therefore, effects three diameters (0.3, 0.4, 0.5 mm) hollow ratios (0, 0.5, 0.7) on efficiency were studied by collecting pulse current, products, during test. All spatial structure designs depend skin effect discharge current. results found that soars with increase when diameter is constant. range 25.2~47.7 MPa. However, correlation between changes from negative positive ratio 0 0.7. phase distribution deduced particle morphology quantity indicates it going be uniform gradually rising When extreme simplification carried out without considering magnetic diffusion process, indicated temperature states along radial a Bessel function depending current density times theoretical enthalpy drives wire. It means desired could obtained efficiently increasing explosion.
