Numerical Simulation of the Common Research Model with Natural Laminar Flow

The Common Research Model with natural laminar flow (CRM-NLF) shows promising numerical and experimental results. This work aims at understanding the aerodynamic characteristics of the CRM-NLF wing under wind-tunnel conditions. The significant effects of turbulent wedges and static aeroelastic deformation are shown. Fluid-structure coupled simulations including laminar-turbulent transition with turbulent wedges show an improved agreement with wind-tunnel data made available by NASA when both effects are considered.
