Kurzfassung

To enhance its capabilities to handle flows with transition, a Reynolds averaged Navier-Stokes solver has been extended with regard to the modeling of transitional flow regions based on transition length models and the intermittency function. Because the full coupling of the solver to an e*-method that predicts the locations of transition onset has not yet been completed, the points of laminar separation are supposed to represent the transition locations in a first step. A method and an algorithm for detecting the laminar separation points are derived, and the intermittency function and two transition length models are implemented and validated for a selected high-lift multi-element test case. The background of the implementation work and the testing of the functionalities of the algorithms are focused on. Details of the implementation, which are consequences of an underlying transition prediction strategy, are outlined. the testing is described and then documented.
