Abstract: |
Large Eddy Simulations (LES) of co-flowing round jets with 33.6 million grid points are carried out using 16 Sun 1 GHz UltraSPARC III Cu processors. An in-depth processor scalability analysis is carried out for an MPI based code for a finite-volume solution of time dependent Navier-Stokes equations. Particular attention is paid to the effect of initial conditions on the spatial development of the co-flowing jet at a Reynolds number of 7,300. The evolution of the turbulence structures is quantified using various discrimination techniques, which compared well with the flow visualisation experiments of Villermaux et al. (1998). |
