TY - JOUR TI - HIGH-PERFORMANCE COMPUTING: APPLICATIONS TO THE NUMERICAL SIMULATION OF TURBULENT FLOWS AU - Breuer Michael AU - Glück Marcus AU - Jovičić Nikola AU - Bartels Christian JN - Thermal Science PY - 2001 VL - 5 IS - 1 SP - 44 EP - 74 PT - Article AB - The present paper summarizes ongoing research and development in the field of Computational Fluid Dynamics on high performance supercomputers at the LSTM Erlangen. Steadily increasing computer performance opens up new vistas for CFD. In the early stage, only two-dimensional predictions based on potential theory were feasible. Nowadays, solutions of the three-dimensional, time-dependent Navier-Stokes equations in complex geometries are state-of-the-art. However, still enough challenges remain for the CFD community. One of the grand challenges is the simulation of turbulent flows. Advanced techniques such as large-eddy simulation and direct numerical stimulation will play a more important role in the future. Based on three different examples, the present work demonstrates, how these techniques can be applied to investigate practically relevant, turbulent flows. The examples cover a wide range of applications, namely the flow in a stirred vessel configuration, the sub- and super-critical flow past a circular cylinder, and the flow around a wing in high-lift configuration. Finally, it is exemplarily shown, how CFD can be combined with other engineering disciplines in order to solve coupled problems such as fluid-structure interaction. Based on an application related to civil engineering, the methodology and its successful application to static as well as dynamic fluid-structure interaction is demonstrated.
