Francis-99 Workshop 3: Fluid structure interaction

Francis-99 is a series of three workshops, which provides an open platform to the hydropower researchers. It gives the possibility to explore capabilities/skills on futuristic turbine design and development. Under the Francis-99 test cases, complete design and data of a Francis turbine are provided. The measurements are conducted on state-of-the-art facility at the Waterpower Laboratory, NTNU. The first workshop was organized during 15-16 December 2014, which focused on the steady state operating condition of the Francis turbine, i.e., best efficiency point, part load and high load. The second workshop was organized during 14-15 December 2016, which focused on the transient operating conditions, i.e., load variation and start-stop. The third workshop was organized during 28-29 May 2019, which focused on fluid structure interactions. In the third workshop, two test cases were provided: (1) Hydrofoil and (2) Francis turbine. The hydrofoil test case aimed to investigate fundamental research, and the turbine test case aimed to investigate applied research. https://www.ntnu.edu/nvks/f99-third-workshop
