Density Measurements on a Delta Wing by Means of Planar Intensity Distribution of Rayleigh Scatteredf aerodynamically relevant flow problems, first tests in the Ludwieg Tube (RWG) of the DLR Göttingen at M=6.8 have been performed. Based on the experiences made during these first tests, the quantitative determination of the density field above a delta wing has been performed at Mach numbers between

Close Coupling of Very High-Bypass Engines in Combination with Take-Off / Landing Configurationss (TPS) were performed in the DA-low-speed windtunnel a Bremen. For these tests on a twin-engine transport aircraft model, the turbofan engine was mounted in the basic and a close coupled position. The results showed, that the negative installation effect for a close coupling can be minimized when t

Numerical investigation of boundary-layer instabilities over a blunt flat plate at angle of attack iory. The Mach numbers range from 2.0 to 2.5 with a unit Reynolds number of 1.26 · 10./. to 0.99 · 10./. at incidences of 0. and −10.. The full Navier-Stokes equations for two-dimensional, compressible flow are solved for the laminar basic flow by application of an Advection Upstream Splitting Method

Application of Two-Parameter Turbulence Models to the Prediction of Two-Dimensional Free Turbulent S the end, as an example of a more complex configuration, the flow field behind an axisymmetric body with jet is calculated. The task of the present study was to examine the reliability of two turbulence models in free shear flows, which were implemented especially for use in wall boundary layers. Kn

Numerical and Experimental Investigations of Flow Induced by Harmonic Motion of a Circular Cylindermensionally stable, moving structures. The two-dimensional velocity field and the force history induced by the harmonic oscillation of a circular cylinder in water at rest at Reynolds number Re=100 and Keulegan-Carpenter number KC=5 was computed accurately in time. Computations have been performed a
