Abstract
The γ -Re θt model, a parallelizable, correlation-based, transition transport model was implemented into the DLR TAU code. Its capability to predict transition has been investigated at one-element airfoils, such as Somers NLF(1)-0416 airfoil and a transonic airfoil of Messerschmidt-Bölkow-Blohm. The influence of relevant input parameters is discussed in terms of predicted transition locations and skin friction coefficient distributions. The standard transition prediction approach in the DLR TAU code is based on the eN-method, a non-local, streamline based approach. Coupling TAU with a boundary layer and stability analysis code enables transition prediction within the RANS solver. The results of both transition prediction methods are compared to each other and the advantages and short-comings of either model are pointed out.
