Simulation results for the third AIAA High-Lift Prediction Workshop obtained with the Bombardier unstructured CFD solver Dragon are presented. A brief description of Dragon is provided. This paper focuses on the results computed on the JAXA High-Lift Configuration Standard Model (JSM), which is representative of a 100-passenger jetliner in a landing configuration. Wind-tunnel data is available to assess the validity of the CFD prediction in terms of forces and moments, pressure distributions and surface flow patterns. The computations were performed on grids generated internally using Pointwise. Simulations were performed to identify the impacts of turbulence model (Wilcox k-ω vs. SST), curvature correction in the turbulence model, transition imposition and grid refinements on the JSM wing-body configuration. Best agreement with the wind-tunnel data was obtained with the k-ω model with curvature correction and laminar-turbulent transition imposed. In addition, Dragon was used to predict the effects of the under-wing nacelle installation on the flow.
