The Juncture Flow Experiment is a new validation class experiment that is simulated here using the Lag turbulence models. The genesis of this experiment was the anomalous side of body separations seen in solutions in Drag Prediction Workshop flowfields. Even the simplest Lag model, the eddy-viscosity version, appears to be quite capable of giving reasonable predictions of this flowfield. With sufficient grid resolution and no internal grid singularities, a very fast and localized oscillation occurs in the wing tip trailing edge region. The predictions for the side of body separation are improved with the enhanced grid system.
