Development of Research Tools to Study Structure and Evolution in the Intermediate Altitude Regime.

Abstract

This report covers the initial research on alternative methods to study aspects of the nonlinear dynamics of low and intermediate altitude fireballs. The research consisted of developing a 2-D vertex-in-cell code, VINCE, and examining the flow field interaction of some simple multiple burst scenarios during the rise and torusing phase of the dynamics. This code will allow the study of a variety of potential structure mechanisms. It was determined that a 3-D version of this code was possible. A final aspect of the research reported here was a cursory study of the problem of small scale structure convention in large codes. Some speculative ideas are presented.
