Renormalization group methods (RNG) have been applied to large eddy simulations of wall regions of channel flows and spectral element RNG simulations of flows in complex geometries were explored. The results predicted wall region streaks accurately at much less spatial resolution than earlier methods. The methods were extended to compressible flows. They have been used to show that the shock region is characterized by large negative values of the divergence indicating tube-like structures. High enstrophy regions reside outside the shock regions. High vorticity regions in incompressible flow tend to be concentrated in tubes, while in compressible flows they tend to be concentrated in sheets. RNG was also applied to k-e modelling of the flow over a backstep. Full simulations were also completed for large Reynolds number turbulence. Keywords: Turbulence, Simulation renormalization group.

2Life, Crime, and Capture of John Wilkes Booth

By George Alfred Townsend

A series of articles by the New York World newspaper's special correspondent covering the assassination of Abraham Lincoln, its background and subsequent events. It should be noted that some statements in this contemporaneous account have since been shown to be inaccurate. Summary by Delmar H. Dolbier
