The Laboratories fo…r Computational Physics & Fluid Dynamics (LCP&FD) are responsible for the the application of advanced analytical and numerical capabilities that are relevant to Navy and DOD programs. LCP&FD has a strong emphasis on the use of the advanced parallel processing supercomputers in research and production computation. LCP&FD has a broad background in advanced computing algorithms, techniques, and applications. LCP&FD objectives are: to develop state-of-the-art analytical and computational capabilities in fluid dynamics and related fields; to establish expertise in parallel processing for large-scale scientific computing; and to perform computational experiments on specific relevant problems using these capabilities. This research was supported by the Office of Naval Research and by the Defense Advance Research Projects Agency. The authors discuss shock-generated turbulence as related to the dynamics of hot gaseous channels produced by laser pulses and electric discharges in gaseous atmospheres. The author present an efficient numerical technique which used the flux-corrected transport algorithm and permits automatic adjustment of the time step to account for both types of behavior. Comparisons of two-dimensional calculations to theory and to experimental data on laser channels show good agreement. The numerical results reveal a mechanism by which the distribution of turbulent scale lengths is generated during energy deposition.
