Kurzbeschreibung (Abstract)
In rans modelling it is common practice to use classical canonical flow cases such as the isotropic decay, the logarithmic law of the wall or homogeneous shear flows for calibrating the model constants. With the help of Lie group analysis a broad variety of invariant solutions (scaling laws) can be derived comprising the latter classical solutions as well as a broad variety of new solutions which have so far not been used for model calibration or development. The symmetry methods provide therefore a very useful tool for the improvement of existing turbulence models or may be a guideline for the development of new models. In the following we will exemplary investigate linear and nonlinear eddy viscosity models as well as Reynolds stress transport models for their capability to reproduce the scaling laws derived from symmetry methods for the fully developed turbulent rotating pipe flow.
