Computation of aerodynamic and acoustic characteristics of NACA0012 airfoil using zonal RANS-IDDES approach

Results of computations of aerodynamic and acoustic characteristics of the NACA0012 airfoil with a blunt trailing edge in the subsonic compressible flow at zero angle of attack are presented. The computations are performed with the use of a modified scheme MP5 proposed in the present work. For turbulence representation, a zonal RANS-IDDES approach combined with a volume generator of synthetic turbulence for creating turbulent content at the RANS-IDDES interface is used. A series of model problems are considered, the solutions of which allow to tune parameters of the proposed numerical scheme and to solve some methodological issues related to post-processing of the results of simulations.
