Residual-based variational multiscale modeling in a discontinuous Galerkin framework

In this work the residual-based variational multiscale method is presented in a discontinuous Galerkin framework. This so-called ‘DG-RVMS’ strategy is developed, extensively verified, and tested on a more complex case.<br/><br/>The proposed DG-RVMS paradigm consists of three principle components. First, the perelement weak form is coupled by...

Finite element discretization of the Spalart-Allmaras turbulence model

The Reynolds-averaged Navier-Stokes equations are numerically solved in a segregated manner, along with the Spalart-Allmaras turbulence model. The Galerkin as well as multiple stabilized finite element formulations are derived for the Spalart-Allmaras turbulence model, and tested for robustness. For a turbulent channel flow and a backward facing...
