What questions will this course answer?

  • Why so many different turbulence models and what are the advantages and limitations of each?
  • What is y+ and how does that affect my turbulent flow simulations?
  • There are so many turbulence models, how do I go about selecting one for my application?

Who should attend?

  • Practicing engineers who wish to learn more about how to choose and apply effective turbulence modelling in their CFD analysis.

Turbulence models based on Reynolds-Averaged Navier Stokes (RANS) equations are the most common and practical approaches for turbulence simulation. Unfortunately, there is no single universally accepted turbulence model that works for all flows and all regimes. Therefore, users have to use engineering judgment to choose from a number of different alternatives since the accuracy and effectiveness of each model varies depending on the application. This course provides the attendees with basic understanding of complexities in turbulence simulation and introduces them to most commonly used turbulence models with their advantages and limitations.

Strong effort is made for the course to be CFD software neutral. However, examples from some of the more well-known and popular software will be used throughout the sessions.


The course is completely code independent.
