Assessment of Reynolds-stress models for aeronautical applications

Three Reynolds-Stress Models (RSMs) have been benchmarked on industrial configurations with aeronautical applications. The models are first compared a zero-pressure-gradient boundary layer, which highlights the differences in near-wall approaches of models. Results then analyzed for Skåre & Krogstad adverse-pressure-gradient layer and Common Research Model (CRM) aircraft two Reynolds numbers. Both cases display improvements using RSMs over eddy-viscosity Spalart-Allmaras model. Two considered second-moment closures better predict growth its shape factor test case, all noticeably improve drag-due-to-lift CRM case.
