Get the answers to these questions and more with this industry-leading, code-independent e-learning course.

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.

NAFEMS e-learning gives you the best of both worlds, giving you real, practical knowledge that you can use day-to-day to improve your analyses.

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.

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.

• A full set of notes in PDF format will be available for download. Each session is presented live and is available for review via a streamable recording.
  
• Personal passwords are provided to allow you to access e-learning backup material via our special bulletin board. Reading lists, homework submissions, supplementary data are all stored as files on the bulletin board.
  
• Interaction via the bulletin board is strongly encouraged to obtain the most from the e-learning class. Typically the board runs for 4 weeks after the last live class sessions, giving you plenty of time to catch up with homework, review and ask questions.
  

Note: homework is purely voluntary!
