v2.03.104 SDLS104 - Coaxial shells under annular flow

Summary

We consider a hardware configuration consisting of two coaxial cylindrical shells, interacting with a fluid flowing in the annular space separating the shells.

The aim of this test case is to validate the fluid-structure coupling model developed in operator CALC_FLUI_STRU for this type of configuration.

Here, we are more particularly interested in the evolution of the modal parameters (frequency and reduced damping) as a function of the fluid flow speed. The reference solution is provided by a calculation carried out with the code MOCCA (MOdèle of Coupling in Annular Confinement).
