Turbulence Modeling for Aerodynamic Flows

Instructed by Dr. Florian Menter, Chief Scientist ANSYS Germany GmbH; developer of the widely used Shear-Stress Transport (SST) turbulence model.

Overview

Whether for aircraft, vehicles, 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.

This 8-hour online course will cover Turbulence Modeling for aerodynamic flows. It will start with an introduction to the challenges of turbulence simulation and the currently used modeling concepts. It will then proceed to provide deeper insight into the main modeling concepts used in today’s industrial/aeronautical CFD simulations, ranging from Reynolds Averaged Navier Stokes (RANS) to Scale-Resolving Simulation (SRS) techniques, like Large Eddy Simulation, and hybrid RANS-LES methods.

Though Ansys CFD software will be used in the course to illustrate example models, the course content will focus on generalized physical principles and applicable to all CFD users, regardless of your CFD software tool of choice.

Learning Objectives:

  • Understand the fundamentals of Turbulence Modeling
  • Understanding the mathematical description of turbulent flows
  • Understand multiple types of advanced turbulent flow models.
Who Should Attend: The course is intended for engineers and physicists at all levels of expertise interested in turbulence modeling. The initial lectures will rehearse the basics of turbulence modeling and will then proceed to more advanced topics of interest also to seasoned CFD practitioners. The audience is expected to have basic knowledge of the subject.

Instructors
Dr. Florian Menter is a world-recognized expert in turbulence modelling. He developed the widely used Shear-Stress Transport (SST) turbulence model, which has set a milestone in the accurate prediction of aerodynamic flows. He has also contributed to the formulation of one-equation turbulence models, advanced near-wall treatment of turbulence equations, transition modelling and unsteady flow models. He has been in charge of the turbulence modelling program at ANSYS for more than 15 years and has been involved in a wide range of industrial modelling challenges. He has published more than 50 papers and articles at international conferences and in international journals. Most recently, Dr. Menter has been involved in the implementation of new turbulence models for unsteady flow simulations, including Scale-Adaptive Simulation (SAS)and Embedded/Zonal LES models. These models are particularly relevant for the many industrial applications where time varying information is essential to the engineering outcomes (such as aerodynamics, acoustics, combustion, fluid-structure coupling, etc.).
