Transient Flows (IAHR_6_S1)

Convenors: Moez Louati (Hong Kong University of Science and Technology), Silvia Meniconi (Perugia University)


Hydraulic transient is known as the rapidly changing flow inducing pressure waves in closed conduits or open channel systems. Despite initially assumed to be one dimensional in nature, recent research has demonstrated that three-dimensional shear and turbulence effects impose significant changes in the nature of the pressure waves generated during transients. The mechanisms for wave propagation are also frequency and mode dependent, creating a myriad of complexities that have driven fundamental research in this area and the development of efficient solution schemes capable of predicting the evolution of these transient waves. This engineering field, which is important for system design and recently found to be valuable for system diagnosis, is being studied by over 500 researchers around the world.
