Calculation of complex three-dimensional configurations employing the DLR-tau-code

Heuristic a posteriori estimation of error due to dissipation in finite volume schemes and application to mesh adaptation

“…In practice the functional may be taken to be an engineering quantity of interest, such as lift or drag. While this theory relies on the Galerkin orthogonality of the finite element schemes used, currently the dominant methods in use for aerodynamic applications are second-order finite volume codes, an example of which is applied in this work, the DLR TAU-Code [11,12]. An alternative but related approach to the same problem which is not considered here is adaptive multiresolution analysis, wherein a hierarchy of discretizations are examined in order to identify the level of solution resolution required locally [13][14][15][16].…”

Evaluation of a Compliant Droop-Nose Morphing Wing Tip via Experimental Tests

“…CFD simulations were carried out using the Tau solver [36,37] with the Spalart-Allmaras turbulence model [38] for the 0% and 100% droop cases to obtain the pressure field over the entire wind tip. The CFD simulations are compared to the pressures and total loads measured experimentally.…”

Optimization of a variable-stiffness skin for morphing high-lift devices

“…Such an approach would require a much more refined aerodynamic analysis to be embedded in the design loop. This calls for a Navier-Stokes solver with some turbulence modelling such as Tau [22] for a high-lift design problem. To avoid the prohibitive associated computational costs, a target shape is predefined based on purely aerodynamic considerations.…”
