Transition Prediction and Analysis of the CRM-NLF wing with the DLR TAU-Code

Promising results are obtained by NASA with the CRM-NLF laminar wing at design conditions. The work presented seeks to develop an understanding of the transition mechanisms involved with the CRM-NLF design under wind tunnel conditions. In addition, the capabilities of DLR tools for RANS-based transition prediction are demonstrated. Particular attention is paid to the effect of turbulent wedges. Numerical results are compared to wind tunnel data made available by NASA.
