“…10 In the case of converging SW, the largest values of the pressure ( 6 Â 10 12 Pa), density ( 9 g/cm 3 ), and temperature ( 16 eV) of the water in the vicinity of the implosion were obtained for a spherical wire array explosion. 9 In these experiments, assuming spherical uniformity of the converging SW and self-similarity of the SW propagation in water, the value of pressure P SW versus the distance from the origin, i.e., radius R SW , increases as P SW / R À1:33 SW , due to fast decrease in the SW surface as S / R 2 SW : Mdivnishvili et al 11 suggested that using boundaries with a geometry providing faster decrease in the SW surface S / R 3 SW , the parameters (pressure, density, and temperature) of matter in the vicinity of the SW's convergence can be increased as compared with the case of a spherical SW implosion. Indeed, in the case of an adiabatic SW convergence, as the surface of the SW decreases faster, due to energy conservation, the energy density behind the SW front must also increase faster.…”
