Abstract: Abstract For a family of variational multiscale methods we perform an a-priori error analysis for inf-sup stable finite element pairs in low-turbulent incompressible flow problems. This is done for underlying layer-adapted meshes with strong Dirichlet boundary conditions and for isotropic meshes with weak Dirichlet boundary conditions. For both approaches we provide first numerical results in a three-dimensional channel at Re τ = 180.
