Fluid-Structure interaction simulation in Nektar++
Mohsen Lahooti (Imperial College London)
A high-fidelity fluid-structure interaction (FSI) solver is developed in the Nektar++ framework. The FSI solver aims at simulation of highly deformable slender structures in largly separated high Reynolds number flows with applications to aeroelasticity and vortex-induced vibration of wind turbine blades. Thikc-strip method is adopted to reduce the computational costs of high-fidelity simulation over highly slender structure. The geometrically-exact composite beam model of SHARPy package is used for simulation of structural dynamics. Virtual partitioning of MPI comunicator is used to support non-constant cross-sections over the strucral span. The application and robusness of solver is demonstrated via several examples.
