Direct Numerical Simulations of Turbulent Boundary Layers on High Performance Computers
نویسنده
چکیده
Direct Numerical Simulations (DNS) of turbulent zero pressure gradient boundary layers have been performed on two high performance computers with di erent 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 ow computations. For the rst time a DNS with a locally re ned grid near the wall has been applied for spatially developing ows. This approach leads to considerable savings of computational time compared to a full grid simulation.

Studies of turbulent boundary layer flow through direct numerical simulation
The objective has been to study turbulent boundary layers under adverse pressure gradients (APG) through direct numerical simulation (DNS). The numerical code is based on a pseudo-spectral technique which is suitable for the simple geometry (flat plate) considered here. A large effort has been put into the optimization of the numerical code on various super computers. Five large simulations hav...

Turbulent flow over an array of wall-mounted cubic obstacles has been numerically investigated using large-eddy simulation. The simulations have been performed using high-performance computations with local cluster systems. The array of cubes are fully submerged in a simulated deep rough-wall atmospheric boundary-layer with high turbulence intensity characteristics of environmental turbulent fl...
متن کاملDirect numerical simulation of hypersonic turbulent boundary layers. Part 1. Initialization and comparison with experiments
A systematic procedure for initializing supersonic and hypersonic turbulent boundary layers at controlled Mach number and Reynolds number conditions is described. The initialization is done by locally transforming a true direct numerical simulation flow field, and results in a nearly realistic initial magnitude of turbulent fluctuations, turbulence structure and energy distribution. The time sc...
متن کاملDirect numerical simulation of separating turbulent boundary layers
Direct numerical simulation of two turbulent boundary layer flows has been performed. The boundary layers are both subject to a strong adverse pressure gradient. In one case a separation bubble is created while in the other the boundary layer is everywhere attached. The data from the simulations are used to investigate scaling laws near the wall, a crucial concept in turbulence models. Theoreti...
