Summary
A solution method is presented for the compressible Reynolds-averaged Navier-Stokes equations on unstructured grids incorporating a high-Reynolds number k — ∈ turbulence model. A cell-centred finite-volume spatial discretisation and an explicit time-stepping scheme are utilised. The influence of added numerical dissipation is discussed and an empirical remedy for the reduction of its influence in viscous layers is proposed. The method is applied to predict the turbulent flow around multi-element aerofoil sections. Results for both the low-speed NLR 7301 and transonic SKF 1.1 wing-flap configurations are presented, showing an overall good agreement with experiment.
