Contributions to the Sixth Drag Prediction Workshop Using Structured, Overset Grid Methods

摘要

Structured-grid solutions obtained for the NASA Common Research Model for the Sixth AIAA Computational Fluid Dynamics Drag Prediction Workshop are detailed. Three different flow solvers were used among the contributors, and the numerical methodologies and turbulence modeling strategies employed by each code are described. Key results for all authors include grid convergence studies for the drag increment of a nacelle and pylon added to a wing-body configuration and a buffet study accounting for static aeroelastic deformation. Additional studies performed include feature-based adaptive mesh refinement and higher-order convective flux discretization, among others.
