TLDR
In this article, a parametric study has been done for a fluid-elastic system consisting of a clamped annular circular plate backed by two cavities by varying the system parameters based on an analytical formulation.Abstract:
A parametric study has been done for a fluid-elastic system consisting of a clamped annular circular plate backed by two cavities by varying the system parameters based on an analytical formulation. The quantification of the coupled frequencies mainly depends on coupling of the acoustic and structural modes. Key parameters like geometry, speed of sound and fluid density influence this coupling significantly. Analysis of this coupling is done by means of a parametric study. The coupling effect in general will be manifested as an added stiffness effect or an added mass effect.read more

Uncertainty Quantification of a Non-linear Rotating Plate Behavior in Compressible Fluid Medium
TL;DR: In this article, uncertainty quantification techniques are applied to a fluid structure interaction (FSI) problem involving a nonlinear rotating disc with surrounding fluid at high pressure without any dissipations, which gives way to a sudden large amplitude oscillation, known as the Hamiltonian Hopf bifurcation in such FSI systems.

TL;DR: In this paper, a comprehensive theoretical model has been developed for interior sound fields which are created by flexible wall motion resulting from exterior sound fields, and an efficient computational method is used to determine acoustic natural frequencies of multiply connected cavities.

TL;DR: In this paper, a set of equations which can be solved for the natural frequencies using real eigenvalue extraction routines is presented, which can synthesize the modal properties of the interacting system from those of the non-interacting fluid and structural systems.
