STRONGLY-COUPLED FLUID-STRUCTURE-INTERACTION WITH LARGE DEFORMATIONS ON A FLEXIBLE HYDROFOIL UNDER FORCED OSCILLATION

This work presents an extension of the existing Fluid-Solid Interaction toolkit from Zeljko Tukovic et al. with a functionality that allows FSI simulations of moving bodies following a forced rotational movement. This finds applications in a wide range of physical problems, such as simulations in turbomachinery. Two different motion solver techniques are combined: 1) The prescribed motion of a solid body, following an already-known motion law, and 2) the deformation of the solid due to the fluid-induced forces. The latter is taken into account by a second motion solver which calculates the velocity diffusion for a moving boundary in a mesh with fixed boundaries.
