Abstract

This chapter presents the high-order Discontinuous Galerkin (DG) solver named MIGALE for the steady solution of the RANS and k − ω turbulence model equations. During the IDIHOM project theMIGALE features have been enhanced both in terms of the prediction capability and solver efficiency, due to the implementation of an Explicit Algebraic Reynolds Stress Model (EARSM) and of the h- and p-multigrid (MG), respectively. algorithm. Several high-order DG results of 2D and 3D subsonic/ transonic turbulent test cases, proposed within the IDIHOM EU project, demonstrated the capability of the method.
