Abstract
Modeling fluid flow around wings is an area of great importance, given the ever more globalized society humanity finds itself in today. Over the years, many different Computational Fluid Dynamics (CFD) models have been utilized to model this behavior, with RANS being the most common and the more computationally expensive DES models being used more in recent years. This study quantified the difference in accuracy for aerodynamic coefficients in the case of 3D printed High-Lift Configuration NACA2412 wings with aileron deflections at 200,000 Re for both approaches. Results from this work showed that, on average, the SST-IDDES approach was better at predicting the coefficient of lift while being worse at predicting the coefficient of drag when compared with acquired experimental data. The IDDES simulations took on average between 24 and 36 times the wall clock time of the RANS simulations to get a useful time sample.
