Water Hammer Analysis using BOSfluids

Surge Analysis

About the course

This course teaches you all the fundamentals of performing water hammer analysis using BOSfluids.
Background knowledge about water hammer phenomena and analyses methods are provided as well as tutorials in performing such analyses in the BOSfluids software. Results are discussed in detail to provide a solid understanding of their interpretation. Next to different water hammer scenarios and their analysis also many real-life cases are provided and associated mitigation measures are discussed.
After this course you are a confident user of BOSfluids that understands good design practices and analysis methods for water hammer phenomena in piping systems.
The course allows you to learn at your own pace and is fully provided online. You receive 1-year unlimited access to all modules, which allows you to perform them over again when you need to refresh knowledge for your work projects.
