Validation of the TAU-code for fuselage-rotorhead applications with moving meshes

Abstract

In the SHANEL-L project in 2009 a simulation of the Eurocopter EC145 fuselage with a model rotorhead was performed with the block-structured solver FLOWer and the unstructured solver TAU 2007 by Eurocopter Deutschland. The results were compared to experimental data from a wind tunnel campaign at the university of Munich. While the results of FLOWer were comparable to the experiment, TAU suffered from an issue in the motion module. Since the solver was considerable improved in the last years, the simulation was repeated in order to demonstrate its applicability for fuselage-rotorhead simulations with moving meshes. The obtained results with the TAU 2011.1.0 release are validated against the experimental data and the FLOWer results.
