Titel:
A mixed/hybrid Dirichlet formulation for wall-bounded flow problems including turbulent flow 
Abstract:
In this study, a new method for the weak imposition of Dirichlet boundary conditions in convection-dominated convection-diffusion and wall-bounded turbulent flow problems is developed. It is based on an embedded Dirichlet formulation which utilises an additional discontinuous stress field for imposing boundary conditions. Values at outflow boundaries may not be sufficiently controllable on underresolved meshes, e.g., when using Nitsche’s method for weak enforcement of Dirichlet boundary condit...    »
