The article considers numerical investigation of the explosion in the water of three and
five spherical charges having the same total weight, arranged in a straight line at a dis-
tance of 10 charge radii taking into account the time delay of triggering. The delay times
are selected from the condition of the simultaneous arrival of water shock waves from the
charges into a certain point in space. The dynamics and parameters of the explosions
with simultaneous blasting and blasting of these charges with different delay times are
compared. It is shown that by choosing the delay time when exploding spaced charges a
substantial increasing of water shock wave pressure can be obtained in a certain range
of the space in a plane of symmetry of charge placement. At the same time the increase in
the delay time shifts the maximum pressure point to the center of the charge symmetry.
Keywords:
explosion, maximum pressure, spherical charge, shock wave, the specific
pressure pulse, numerical simulation.
