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...

The non-ideal behavior of aluminized explosives significantly affects the characteristics underwater explosion shockwaves, rendering classical model for shockwaves difficult to apply. In this paper, we analyze shockwave a new generation and propose explosive incorporating parameter correction function controlled by Al/O ratio. First, conducted tank experiments obtain four groups ratios paramete...

Structural health monitoring of cracked structures is one of beloved subject of researchers recently. Consider of crack behavior in the water and energy pipeline is important because of environmental problems. In this paper consider of crack parameters in the underwater pipe subjected to mechanical transient load is investigated. For this purpose, three- dimensional parametric model of cracked ...
