Learn how to apply turbulence modeling successfully.

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 judgement 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.

Who Should Attend?

Engineers aiming to use CFD as a reliable predictive tool for complex flow problems.

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

Ideally, the participant should have some knowledge of Computational Fluid Dynamics analysis, but this is not essential.
