Automatic Transition Prediction for Three-Dimensional Aircraft Configurations Using the DLR TAU Code

Abstract

SummaryA Reynolds-averaged Navier-Stokes solver, a laminar boundary-layer code and a fully automated local, linear stability code for the prediction of TollmienSchlichting and cross flow instabilities were coupled for the automatic prediction of laminar-turbulent transition on general aircraft configurations during the ongoing flow computation. The procedure is applied to different threedimensional wing-body configurations and the sensitivity of the coupled system to a variety of coupling parameters is investigated.
