v8.01.108 FDLV108 - Calculation of damping added in annular flow (variable density)

Summary:

This fluid-structure test involves calculating the mass and damping added to a cylindrical structure subjected to an annular flow that is assumed to be potential. Mass and damping added by the flow on the structure are calculated for an upstream speed of \(4{\mathrm{m.s}}^{-1}\), on a 3D model for the fluid and shell for the structure. The structure has a rotational movement around a pivot located at the downstream end of the cylinder with respect to the flow. The advantage of the test lies in taking into account a fluid domain with a density of not homogeneous.
