Abstract
In this paper advanced turbulence simulations at Reynolds numbers in the range of 1.4x10^5-8,5x10^5 will be carried out by means of large-eddy simulations. Numerical simulations using unstructured grids up to 90 million of control volumes have been performed on Marenostrum Supercomputer. One of the major outcomes of this work is to shed some light on the wake topology and flow features at critical and supercritical Reynolds numbers, whilst at the same time to study the s...
