Whether for cars, trucks, aircraft, or wind turbines, aerodynamics is a critical aspect of improving energy efficiency. Aerodynamics is a complex science — calculations need to be performed with a high degree of precision and accuracy, since every 1 percent of change in aerodynamic drag or lift has enormous implications on machine performance. Aerodynamic simulation, therefore, requires accurate flow solvers, comprehensive turbulence models, and precise geometry handling.

In this 60-minute Webinar, Dr. Florian Menter, a world-renowned turbulence modeling expert, will present Stress-Blended Eddy Simulation (SBES) — a new paradigm in hybrid RANS-LES modeling — with a focus on aerodynamics and other applications. Large Eddy Simulation (LES) is impractically expensive in the near-wall region. However, Reynolds-Averaged Navier-Stokes (RANS) models are well-suited for wall boundary layers. Therefore, hybrid models such as SBES that use RANS for the wall boundary layers and LES away from the walls provide the best accuracy for practical turbulent flow simulations. The SBES blending function clearly shows the zones of RANS and LES usage. The SBES methods presented in this Webinar are now commercially available for aerodynamics and other complex flows.

Participants will learn about the latest advances in aerodynamics simulation as our experts discuss studies of global leaders in the automotive and aerospace industries. An audience Q&A will follow the speaker presentations.
