Application of Flux-Corrected Transport to TTCP Joint Launch Blast Computational Effort

摘要

The method of Flux-Corrected Transport (FCT) was developed as a means for solving systems of hyperbolic equations in such a way that physically positive quantities like mass and energy density remain possitive. Its principal application has been to compressible fluids, i.e., fluids in which some of the flow speeds are comparable with or greater than the local speed of propagation of waves in the medium. During the past decade the method has been extended and generalized in a number of important respects. A general-purpose FCT hydrocode was used to treat two muzzle blast test problems. Analysis of the results and comparison with data indicates that the results are physically realistic and, within the modeling assumptions, highly accurate. The FCT simulation model used runs on the Cray-1 and on smaller mainframe computers including the VAX and the multitasking array processors in our Graphical and Array Processing System.
