Advanced Simulator Power Flow Technology/Advanced Radiation Simulation Volume 2: MHD Modeling of POS and Power Flow
Abstract
This is the second of 3 volumes describing work for the Advanced Simulator Power Flow Technology/Advanced Radiation Simulation Program. This volume, for FY95, deals with analytical, computational and experimental studies of power flow in vacuum feed and switch regions of pulsed power, inductive energy store systems. The first section analyzes by means of a two-dimensional MHD code the evolution of density of the opening switch plasma in the Hawk generator and its dependence on electrode geometry. The following three sections describe the Mach2 MHD code and its application to the design of a novel switch configuration and to the simulation of ACE-4 flashboard experiments. In Sections 5 and 6 the Mach2 code is discussed, including the search for algorithms for the electron Hall effect. In Section 7 the two-dimensional Delta MHD code is described with its analysis of Tandem Puff experiments on ACE 4. Section 8 addresses the new user-friendly, SPICE-MIRIAD based circuit code. Sections 9 and 11, respectively, report improvements to the fast running two-dimensional snowplow model. And Section 10 reports the results from measurements and analysis of current losses in convolutes measured on the ACE 4 coaxial configuration. The contract option work is discussed in the Executive Summary.
