Application of Reynolds Stress Models to High-Lift Aerodynamics Applications

摘要: A recently proposed explicit algebraic Reynolds stress model (EARSM) based on a nonlinear pressure strain rate has been implemented in an industrial CFD code for unstructured grids. The new EARSM was then used to compute the flow around typical three element high-lift devices transport aircraft both 2D and 3D. For mean flow, various angles of attack have investigated. Two different grids used, one coarse grid with 35,000 nodes fine 340,000 nodes. Furthermore, 3D take-off configuration including fuselage computed using computational about million points. case pre-stall attack, makes fair predictions. higher baseline show large sensitivity transition point location. original setting leads premature stall while alternative gives predictions that are good agreement experiments. lower there indications minor improvements. One angle close maximum lift compared previous computations. No significant differences were found EARSM. Also convergence effort by comparable
