Computer Modeling and Experimental Validation of Losses in a Strip Geometry Explosive Magnetic Flux Compression Generator
Abstract
A computer program to predict the performance of a strip geometry explosive magnetic flux compression generator (MCG) was developed and validated. The program contains five separate models of the MCG, two theoretical and three empirically based. The first model is a theoretical lossless flux conserved model. The second model accounts for resistive losses due to plate resistance and a flux diffusion equivalent resistance. The first empirical model models the remaining losses as a slipping loss. The second empirical model adjusts the flux conserved model with an additional time varying inductance. The final empirical model is a simple flux trapping efficiency model. Actual MCG experiments were conducted using the Air Force Weapons Laboratory's strip MCG. The data from these experiments was used to validate the computer program. Input currents varied from 294.0 KA to 1100.0 KA with resulting output currents of 2210.0 KA to 10261.0 KA and current amplification factors between 6.29 and 15.75. (Author)
