Abstract
The Japan Aerospace Exploration Agency standard model high-lift configuration was analyzed computationally using both the OVERFLOW and LAVA codes for the third AIAA High-Lift Prediction Workshop. Simulations were performed both with and without the nacelle/pylon feature as prescribed by the workshop test cases. Without the nacelle/pylon, evidence of multiple solutions was observed when a quadratic constitutive relation was used in the turbulence modeling; however, time-accurate simulations seemed to favor one solution over the other. With the nacelle/pylon, no evidence of multiple solutions was observed. Laminar–turbulent transition modeling was also applied to the configuration, and it had an overall favorable impact on the lift predictions.
