DLR/DGLR Workshop in Braunschweig

3. - 4. Dezember 2003

DLR/DGLR Workshop on Novel Techniques for the Solution of the Compressible Euler and Navier-Stokes Equations for Aircraft Design


During the last decade, considerable progress has been made in the development and validation of numerical methods for aerodynamic design applications in aerospace industry. Today, CFD has matured to a point where it is widely accepted as an essential tool complementary to wind tunnel experiments and flight tests. Complex Navier-Stokes methods have advanced from specialized research techniques to practical engineering tools for a vast number of industrial problems on a routine basis. However, despite recent advances in CFD, flow prediction for complete aircraft is still a challenge, because requirements for simulation accuracy and efficiency are constantly rising in industrial applications. It is crucial to reduce the response time for complex simulations, although the relevant geometries and underlying physical flow models are becoming increasingly complex. Moreover, there is a demand for tools that can perform reliable numerical simulations of the whole flight envelope, requiring multi-physics simulations. In order to meet future demands of the aircraft industry with respect to more environmentally friendly, safer and economical aircraft, substantial improvements in various fields such as mathematical algorithms, physical modelling, validation and uncertainty estimation are necessary.

Workshop objectives

The aim of the workshop is to discuss innovative numerical methods for solving the compressible Euler and Navier-Stokes equations. During the last few years many new techniques and concepts have been developed and investigated at research level and some of them have demonstrated high potential to substantially improve simulation capabilities at least for academic test cases. The workshop should serve as a forum to discuss novel numerical methods between applied mathematicians, CFD researchers and engineers. Main topics are: innovative spatial and time discretization schemes, higher order methods and novel adaptation techniques. Besides confirmed keynote lectures, the workshop is open for contributions.
