Abstract
This work is part of the development of a new generation CFD solver, Argo, based on the discontinuous Galerkin Method (DGM), specifically targeted towards accurate, adaptive, reliable and fast DNS and LES of industrial aerodynamic flows. Several aspects were investigated in IDIHOM. A first activity was the optimisation of the parallellisation strategy, resulting in highly efficient scaling, demonstrated on some of the largest computers in Europe. A second activity concerned the assessment and validation on several academic benchmark problems of the capability of DGM to perform direct numerical simulation (DNS) and (implicit) Large Eddy Simulation (iLES). Two moderately complex flows are treated, namely the ILES of the transitional flow in the low pressure turbine cascade T106C and the isothermal jet issueing from the JEAN nozzle.KeywordsDiscontinuous Galerkin Method (DGM)High Performance Computing (HPC)Direct Numerical Simulation (DNS)(implicit) Large Eddy Simulation ((I)LES)Transitional flowIndustrial CFD
