A one-dimensional hydrodynamic set of simulations of converging
SSW generated by underwater electrical explosion of
wire arrays with different array radii and different deposited
energy has shown that for each wire array radius there exists
an optimal duration of the energy deposition that provides
maximum pressure and temperature at the point of observation.
Thus, the dependences obtained allow one to choose
the cylindrical wire array and pulsed power generator properly,
which would allow one to achieve maximal pressure
and temperature values at the implosion axis. The physical
phenomenon behind this result is related to the energy
dissipation by the propagating SSW towards the implosion
axis in the case when the SSW time of flight is significantly
larger than the time of exploding array expansion. In the
opposite case, the SSW arrives at the implosion axis at a
time when only a part of the energy realized during the array
expansion is transferred to the generated water flow. Based
