• A Reynolds averaged Navier Stokes; (RANS) solver, a laminar boundary layer code, and an eN database method for transition prediction were coupled in order to perform RANS computations of two dimensional high lift multielement systems with automatic laminar turbulent transition prediction and transitional flow regions. It will be shown that the coupled system represents a RANS based computational fluid dynamics tool that provides accurate values of the transition locations during the ongoing RANS computation automatically and fast without the need for the intervention by the code user. Thus, RANS computations of two dimensional high lift multi element configurations with transition can be carried out without a priori knowledge of the transition characteristics of the specific flow problem. The coupling structure and the underlying algorithm of the transition prediction procedure as well as the physical modeling of transitional flow regions and their generation in the RANS computational grid are described. The testing of the transition prediction procedure is described and documented. The computational results are compared to experimental data. [PUBLICATION ABSTRACT]
