The objective of this work is to show the effectiveness of a high-order accurate Discontinuous Galerkin (DG) space discretization in the numerical simulation of the 3D compressible turbulent flow through a turbine cascade (MTU T106A). The turbulent flow field is computed by means of the Reynolds Averaged Navier-Stokes (RANS) equations with closure provided by the k-ω turbulence model and an Explicit Algebraic Reynolds Stress Model (EARSM). Results obtained with both models will be analysed and compared.

Abstract
The objective of this work is to show the effectiveness of a high-order accurate Discontinuous Galerkin (DG) space discretization in the numerical simulation of the 3D compressible turbulent flow through a turbine cascade (MTU T106A). The turbulent flow field is computed by means of the Reynolds Averaged Navier-Stokes (RANS) equations with closure provided by the k-ω turbulence model and an Explicit Algebraic Reynolds Stress Model (EARSM). Results obtained with both models will be analysed and compared.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
