Extreme water state produced by underwater wire-array electrical explosion

The generation of an extreme water state 130 GPa, 5000 K, and 3.4 g /cm3 which is characterized as dense plasma at the axis of a converging shock wave is reported. A 4 kJ pulse generator was used to explode a 40 Cu-wire array, generating a cylindrical shock wave. The measured shock wave trajectory and energy deposited into the water flow were used in hydrodynamic simulations coupled with the eq...

Characteristics of Fe-Cr-Al Alloy Nanopowders Prepared by Electrical Wire Explosion Process under Liquid Media

Fe-Cr-Al alloy nanopowders were successfully prepared by electrical wire explosion method in ethyl alcohol media. The formation of FeCr-Al alloy nanopowder was monitored by X-ray diffraction. The alloy powders have spherical shape and nanometer size. The alloy powders prepared by the electrical wire explosion method have main crystal structures of bcc Fe-Cr alloy. The geometric mean diameter an...

A Second Order Accurate Method in Simulation of Underwater Explosion

In this paper, a numerical scheme is proposed for the multi-fluid compressible flows. This method is applied to the problem of underwater explosion. The proposed scheme is basically the extension of Godunov method in gas dynamic problems to the multifluid environments and is second-order accurate in space. In this method, also, the problem of artificial mixing of two different phases on Euleria...

Dynamics Behavior investigation of Concrete Gravity Dams by Deep Underwater Explosion Method

In this research, a deep explosion in the reservoir of a concrete gravity dam has simulated by the coupled Euler –Lagrange finite element method. The validity of explosion hydrodynamics pressure has compared with Taylor empirical formula.  The surface sloshing not considered due to deep explosion. The dam and its retained water excited by detonating large explosive charges in deep water upstrea...
