Elements of Turbulence Modeling

This 2-session, live online course will cover a range of topics including:

• Understanding turbulence, energy cascade & vortex stretching,
• Turbulence scales, time averaging and closure problems,
• Boussinesq hypothesis,
• Various RANS-based models,
• Wall treatment,
• y+, Detached Eddy and hybrid models.

You can either attend the live sessions or take the course on-demand at your leisure.

What will you learn?

• Understanding turbulence and various turbulence scales,
• Various approaches in simulating turbulent flows,
• Wall treatment and y+,
• Advantages and limitations of various approaches,
• Procedure to select an appropriate model.

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.
