The phase state of thin (∼1 μm) layer of water adjacent to the surface of rapidly heated thin wire 100±50 μm in radius is analyzed by computer hydrodynamic calculation. It is shown that when heating of a wire to a temperature of 420 °C is achieved in less than ∼500 ns, the trajectory of the phase state is contained in the liquid part of the phase diagram. This suggests additional proof of and an explanation for the absence of shunting plasma discharge in fast underwater electrical wire explosions.
