Buckingham, A C

This concerns the observed random changes to shock transitional velocity, density, and temperature induced when shocks interact with turbulence. This interaction may be useful as a diagnostic for ascertaining the distribution of interaction energy between competitive acoustic, entropy and vortical modes. Numerical procedures are used here to supplement physical experiments. The results are obtained from use of an ALE'' finite-difference code method with viscoelasticity (SHALE), a hybrid Euler/Lagrange pseudospectral method, and a Monte-Carlo random-choice procedure. The latter magnifies the shock front transition region generating PDF-transition profiles. 10 refs., 5 figs.
