Summary
This paper presents the strategy and application of the coupling of a Navier-Stokes solver with a transition prediction method. For industrial applications the coupling of the solver to an database method, based on local linear stability theory, results in a program system that is able to automatically handle transition prediction. The solver was coupled to a transition prediction module, consisting of a boundary layer method for swept, tapered wings and engineering transition prediction methods, a.) two algebraic, empirical transition criteria and b.) an eN-database method for Tollmien-Schlichting waves. The sensitivity of the coupled system with regard to a change of system parameters was investigated. It could be shown that for some of the parameters the sensitivity does not exist and that it is very low for the others.
