Abstract

The simulation of movable control surfaces is of interest for many applications in aerospace engineering, but it is challenging to perform high-fidelity computations considering them. Generating a new mesh for each deflection angle is computationally expensive, so alternative approaches that allow using only one mesh have been developed in the recent years. This work gives an overview of the available methods for modelling of control surfaces, with special focus on the ones that consider the spanwise gaps between the wing and the control surface. This includes the usage of the Chimera technique combined with mesh deformation as well as a sliding interfaces boundary condition. Their performance has been tested with the DLR MULDICON configuration.
