Journal ArticleDOI
Shock-Wave/Boundary-Layer Interaction Control Using Three-Dimensional Bumps for Transonic Wings
TL;DR: In this article, three-dimensional bumps have been developed and investigated on transonic wings, aiming to fulfill two major objectives of shock-wave/boundary-layer interaction control, that is, drag reduction and buffet delay.
Journal ArticleDOI
Design and Wind-Tunnel Verification of Low-Noise Airfoils for Wind Turbines
TL;DR: In this article, a method for the prediction of the airfoil trailing-edge far-field noise is presented, which employs the XFOIL analysis code to determine the initial and boundary conditions for a subsequent boundary-layer analysis using the finite-difference code EDDYBL featuring a Reynolds stress turbulence model.
Journal ArticleDOI
Drag Reduction and Shape Optimization of Airship Bodies
Thorsten Lutz,Siegfried Wagner +1 more
TL;DR: In this paper, a tool for numerical shape optimization of axisymmetric bodies submerged in incompressible flow at zero incidence has been developed, where a source distribution on the body axis was chosen to model the body contour and the corresponding inviscid flowfield, with the source strengths being used as design variables for the optimization process.
Journal ArticleDOI
Trailing edge noise reduction of wind turbine blades by active flow control
TL;DR: In this article, the authors investigate a route to reduction of the turbulent boundary layer-trailing edge interaction noise, which is generated by surface pressure fluctuations beneath a turbulent boundary and scattered at the trailing edge of wind turbine blades.
Proceedings ArticleDOI
Numerical and Experimental Validation of Three-Dimensional Shock Control Bumps
Benedikt König,Martin Pätzold,Thorsten Lutz,Ewald Krämer,Henning Rosemann,Kai Richter,Heiko Uhlemann +6 more
TL;DR: In this paper, numerical and experimental studies have been performed to show the potential for drag reduction of an array of discrete three-dimensional shock control bumps, specifically designed by means of CFD-based numerical optimization for wind tunnel testing on a modern transonic airfoil.
