Abstract: Abstract Direct Numerical Simulations (DNS) of turbulent zero pressure gradient boundary layers have been performed on two high performance computers with different architectures. The one, a Cray T3E-900, is a massively parallel computer (HLRS computing center, Stuttgart/Germany). The other, a Fujitsu VPP700, is a Vector-parallel computer (Leibniz Computing Center, Munich/Germany). Both computers are well suited for large-scale flow computations. For the first time a DNS with a locally refined grid near the wall has been applied for spatially developing flows. This approach leads to considerable savings of computational time compared to a full grid simulation.
