Understanding Turbulence in Fluids using Direct Simulation Data

Publication Summary

Since 1994 the DNS-Turbulence Consortium has been using the Cray T3D and T3E computers at Edinburgh Parallel Computing centre to conduct space-and time-resolved calculations of turbulent flow. A variety of cases have been studied in detail including the first resolved calculation of turbulent boundary layer reattachment following laminar separation, the response of turbulence to three-dimensional distortion and the response of turbulence to separation. The data from these simulations have been used to test and improve turbulence models. In this paper the progress that has been made in the last three years is reviewed.
