Conference paper


Variational multiscale discretisations for turbulent flows, first introduced by Hughes [1] have been shown to produce accurate results with relatively simple modelling assumptions. A particularly flexible discontinuous Galerkin variant has been developed by Collis [2]. Continuous Galerkin discretisations, however, can be advantageous in that their low implicit dissipation simplifies the calibration of subgrid-scale models. Recent work has indicated that combining continuous methods with weak boundary conditions can result in improved accuracy [4], while adding some of the flexibility inherent in discontinuous methods. We consider a continuous-Galerkin variational-multiscale method combined with penalty-based weak boundary conditions, and describe the relation of the latter to traditional wall-stress models.
