of an underwater explosion by splitting the charge

into separate parts

We numerically investigated the simultaneous explosion in the water of three and five

spherical charges located in line with a spacing of 6 and 10 radii of the same charges.

Comparison of the parameters of the explosion of a single and three and five charges

of

the same mass showed that

in the plane of symmetry of the charges location there is an

increase of the maximum pressure and the specific impulse of the aqueous shock wave up

to 80 %

. As the distance between the charges is increasing, the gain on pressure decreas-

es, and it increases on the specific impulse.

Keywords:

explosion, the maximum pressure, spherical charge, the shock wave, the spe-

cific impulse of pressure, numerical simulation, pressure diagrams.
