Models and Analysis of Wire Explosions Using TRAC II Simulations
In order to understand the dynamics of Z-pinch irnposions of thin wires in pulsepower accelerators, it is necessaryto understandthe physicalprocessby which the initially solid wires are coverted into plasma by rising current. For this purpose, we model wire explosions using TRAC II, a tw~demensional MHD code, in three distinct cases: pure tungsten, impure tungsten, and gold-plated tungsten. We ...
متن کاملSignal Analysis and Waveform Reconstruction of Shock Waves Generated by Underwater Electrical Wire Explosions with Piezoelectric Pressure Probes
Underwater shock waves (SWs) generated by underwater electrical wire explosions (UEWEs) have been widely studied and applied. Precise measurement of this kind of SWs is important, but very difficult to accomplish due to their high peak pressure, steep rising edge and very short pulse width (on the order of tens of μs). This paper aims to analyze the signals obtained by two kinds of commercial p...

متن کاملInfluence of an Inclusion on Multi-Pass Copper Shaped-Wire Drawing by 2D Finite Element Analysis
The size and length effects of an inclusion on multi-pass copper shaped-wire drawing were investigated. For this purpose, an experimental investigation on optimal die half-angle was conducted. Based on experimental data of optimal die half-angle, wire and inclusion deformations, drawing and hydrostatic stress of copper shaped-wires that contain an inclusion were calculated by two-dimensional fi...
