Turbulence Models in FLOWer Results for industrially more relevant test cases of the flow around two different wing-body configurations and a three-element airfoil are presented, confirming the findings for the simple geometries at least under transonic conditions. From this, recommendations for the choice of suitable models are derived.

The Continuous Adjoint Approach in Aerodynamic Shape Optimizationmization methods based on the calculation of the derivatives of the cost function with respect to the design variables suffer from the high computational costs if many design variables are used. However, these gradients can be efficiently obtained by solution of the continuous adjoint flow equations.

Transition Modeling in FLOWer — Transition Prescription and Predictionthods were incorporated into the code and an infrastructure was built up in order to handle the underlying transition prediction strategy which results in an iteration process within the solution process of the RANS equations. Finally, physical models for the modeling of transitional flow were implemented and tested.
