The Dlr Tau-code: Recent Applications in Research and Industry
نویسندگان
چکیده
This paper gives an overview of the TAU-Code, DLR’s system for complex flow simulations on unstructured hybrid grids. Starting from a short description of the system and its components, e.g. mesh adaptation or grid deformation, its basic capabilities are discussed. Thereafter recent and on-going developments are presented, such as the adjoint approach or a pilot installation exploiting structured grids. The remainder of the paper discusses a number of recent applications of varying complexity, both from DLR and aircraft industry, such as simulation of half-model effects in wind tunnels, effects of trailing edge devices on full aircraft configuration, flow about a helicopter fuselage and generic Arianne-type launcher, full aircraft simulations such as A380-type airplane with undercarriage or complete EF2000 .
