The large equivalent shallow-depth explosion problem is very significant in the field of naval architecture and ocean engineering, as such explosions can be used to attack demolish ships anti-ship missiles. In current work, a refined numerical study flow-field characteristics carried out using self-developed Eulerian finite element solver. First, model validated against theoretical results smal...

Two interacting supersonic water jets and collisions of a jet with an aluminum target are studied experimentally by hydrodynamic simulations. Supersonic form, when shocks generated underwater electrical explosions conical wire arrays converge. The supplied ∼250 kA, ∼1 μs rise time current pulse. Underwater explosion two placed face to produces propagating in air velocities ∼2.5×103 m/s leading ...

The characteristics of cavitation and atomization induced by underwater explosion near a free surface have been investigated the multiphase fluid model based on two-fluid phase transition. This numerical method can provide transition between liquid its vapor phases during shock wave rarefaction propagation at any time in explosion. detailed density, pressure, vapor, volume fraction contours zon...

underwater acoustic wireless sensor network (uawsn) use acoustic signalsto transmit data. acoustic signals in underwater environment have high bit errorrate, long propagation delay and limited bandwidth. another constraint in uwasnis energy. due to these constraints, design of energy and bandwidth efficient andpropagation delay aware mac protocol is a great challenge in uwasn.underwater sensor ...

Abstract This paper aims to study the effects of different water depths on properties emulsion explosives by use an explosive underwater explosion test system for hydrostatic pressure under condition 0.2% sodium nitrite sensitized blasting model experiments. The results showed that experiment designed simulation equipment can be used in performance sample compression state explosion. It better ...
