Committee on Transient Flows
Our aim is to provide with a framework to the transient group community within IAHR association. To the date, there are no other international research associations with a specific representation to hydraulic transients. Eventually, our vision is to organize individual IAHR symposiums or conferences on transients and start to have a sub-theme or a theme on transient in future IAHR congress.
The main focus areas of the working group include:
Transient waves theory in hydro-systems
Hydro-system diagnosis by means of transient waves
Waves-structure interaction in hydro-systems
Geysers in storm-water and combined sewer systems
Computational transient flows modeling (in closed or opened conduit flows)
Transient-turbulent flows (in closed or opened conduit flows)
Field works: case studies, practical applications and projects
