Scope of the workshop

Scope of the third workshop is fluid structure analysis under steady state operating conditions. More specifically, parameters such as study of mode-shape, nodal-diameter, deformation, fatigue loading, estimation of fatigue life, individual/combined natural frequencies, hydrodynamic damping, harmonic response, etc. will be investigated².

The Hydrofoil test case focuses on fluid structure analysis (one-way or two-way) and to study one/many of the above parameters. Basic/fundamental research is the main objective and how the approach (applied on hydrofoil) can be useful for the complex structure such as turbine blades. CFD analysis of the hydrofoil will be welcomed if sophisticated turbulence modeling approaches such as, detached eddy simulation, large eddy simulation (LES), hybrid RANS/LES, and direct numerical simulation (DNS), are used that will help to understand the mechanics of vortex shedding and the resonance. In addition to the harmonic response, modal analysis, acoustic model, two-way FSI is also encouraged.
The turbine test case focuses on fluid structure analysis (one-way and/or two-way) and to study one/many of the above parameters. CFD analysis in turbine is NOT the focus as it is already covered under the previous Francis-99 workshops.
