Abstract

Initially the measurement of the flow around a swept wing airfoil was planned within the AFDAR project. During the project it was decided to select the flow over periodic hills as one of the main test cases as this flow is relevant for aerodynamic configurations but also for the validation of numerical flow simulation methods in aerodynamic research. The multitude of phenomena on different scales in both, space and time are best suited to explore the algorithms for data evaluation and analysis developed in the project. The flow over periodic hills is a common test case for the validation of numerical flow simulations (see ERCOFTAC test case Nr. 81). The numerical prediction is very difficult, since flow separation and reattachment are not fixed in space and time due to the smooth geometry (Temmerman et al., 2003; Fröhlich et al., 2005).
