We present simulations with the Automated Zonal DES (AZDES) approach on the supercritical OAT15A airfoil and the Common Research Model (CRM) airplane configuration. Comparing URANS and AZDES simulations the shock prediction capabilities of URANS can be preserved. Turbulent structures in the wake are resolved in LES mode, which enables investigation of the propagation of turbulence in the wake. AZDES was shown to provide consistent results across different grids for the OAT15A airfoil. Validation using experimental data for the CRM showed good agreement in terms of wing pressure distributions.
