NAFEMS Advanced CFD Course
3rd to 5th April 2018, Singapore

“Even experienced CFD users find choosing the right turbulence model a challenge. In his course on Turbulence, Kamran provided exceedingly useful and clear descriptions of the available models in most CFD codes. The course was very helpful in deciding which turbulence model should be used in order to provide the best combination of accuracy and efficiency. I would strongly recommend this course to all CFD users.” Keagan Chee @NING Research

Motivation

The NAFEMS Advanced CFD course provides an in-depth practical and structured understanding of the most important technical aspects of CFD simulation which are the basis for robust CFD solutions across a broad range of application areas.

The course is broken into two parts. Part One covers the fundamentals of CFD and serves as an introduction for those relatively new to CFD and a refresher for experienced users. This helps to ensure all students have a common level of understanding and are ready for the more advanced concepts. In Part 2, a full day is spent on turbulence modelling. It explains the various models available and how, why and when to use them. The final day cover other advanced CFD capabilities, which are becoming much more commonly used, such as multiphase flow and fluid structure interaction. We finish the course with a discussion of steps required to perform verification and validation of the CFD solution.

Who Should Attend?

This course is aimed at practicing engineers who wish to learn more about how to apply Computational Fluid Dynamic techniques to their particular problems in the most effective manner. This course is useful for managers who review CFD reports and contract suppliers.

The material presented is independent of any particular software package, making it ideally suited to current and potential users of all commercial finite element software systems. This course is a must for all engineers aiming to use CFD as a reliable predictive tool for the analysis of fluid and gas flow as well as those working on multi-physics problems where CFD is coupled with FEA or other simulation software.

Companies moving into CFD technology to improve product designs or assess prototype failures or speed the design process will benefit from sending key engineers to this course.

The course is open to both members
and non-members of NAFEMS.
