Joint Symposium of DFG FOR 1066 and DLR-Airbus C²A²S²E: “Simulation of Wing and Nacelle Stall” 22-23 June 2010 in Braunschweig, Germany : Symposium Co-Chairmen: Prof. R. Radespiel and Prof. N. Kroll Reliable simulations of flow separation on airfoils, wings and powered engine nacelles at high Reynolds numbers represent great challenges in defining suitable mathematical models, computing numerically accurate solutions and providing comprehensive experimental data for the validation of numerical simulations. Additional scientific problems arise from the need to consider airframe-engine interactions and inhomogeneous onset flow conditions as real aircraft operate in atmospheric environments with sometimes ... |

25 Years of Particle Image Velocimetry in Aerodynamics September 23 - 25, 2009, DLR-Göttingen The twenty fifth return of the day when the first PIV measurements in a wind tunnel have been performed in Göttingen is considered to be a good opportunity to commemorate the early developments of the PIV technique and to contrast the technical possibilities of those days to the state-of-the-art of PIV today. |

20th Liepmann-Ludwieg-Seminar May 04, 2009, DLR-Göttingen The annual "Liepmann-Ludwieg Seminar" was established in 1987 by the Graduate Aeronautical Laboratories, GALCIT, and the German Aerospace Center, DLR. It was ideated by the former director of GALCIT, Prof. Hornung, with the aim of fostering international cooperation among young scientists working in the field of fluid mechanics.

3rd PSP Course - Application of Pressure Sensitive Paint - Theory and Practice September 7 - 11, 2009, Göttingen For investigations of pressure distributions on wind tunnel model surfaces with high spatial resolution new experimental techniques, such as Pressure Sensitive Paint (PSP) are required. Using this non- intrusive optical pressure measurement technique, spatial structures and/or rapid temporal or spatial changes of aerodynamic phenomena (transition from laminar to turbulent flow, coherent structures, pitching airfoils in transonic flows with shocks, rotors, test facilities with short run time and different flow temperature etc.) can be investigated. The PSP technique has also expanded from the measurement of steady state pressures to include both periodic and unsteady phenomena to study the instantaneous structure of pressure fields in various areas of fluid mechanics. |

18th PivCourse - Application of Particle Image Velocimetry - Theory and Practice March 22 - 26, 2010, Göttingen The main interest of todays research in fluid mechanics is more and more directed to problems where unsteady and separated flows are predominant. For investigations of flow fields with pronounced spatial structures and/or rapid temporal or spatial changes (transition from laminar to turbulent flow, coherent structures, pitching airfoils in transonic flows with shocks, rotors, test facilities with short run time, etc.) new experimental techniques, such as Particle Image Velocimetry (PIV) are required which allow to capture the flow velocity of large flow fields instantaneously. |
