Summary form only given. Magneto-hydrodynamic simulations provide a powerful tool for improving our understanding of the complex physical processes underlying the behavior of wire array Z-pinches. With the advent of large scale parallel computing and three dimensional models, it is now becoming possible to model the entire plasma volume with sufficient resolution to capture the important physical...
We present 3D resistive MHD modeling of the implosion and stagnation of single and nested wire array Z-pinches on the Z generator. Compact tungsten wire array Z-pinches have proven to be a powerful, reproducible X-ray source. The use of nested wire arrays has provided further gains in X-ray power and the pulse shaping capability necessary for application to inertial confinement fusion. Radiography...
Summary form only given. Development of a predictive computational model for wire array z-pinches has been inhibited by the 3D nature of the dynamics. We have developed a 3D computational model for simulating cylindrical wire array z-pinches. In lieu of trying to simulate individual wires in the array from the beginning of the initiation phase, which is computationally impractical, we have incorporated...
