Fluid–structure interaction (FSI) is the interaction of some movable or deformable structure with an internal or surrounding fluid flow. Fluid–structure interactions can be stable or oscillatory. In oscillatory interactions, the strain induced in the solid structure causes it to move such that the source of strain is reduced, and the structure returns to its former state only for the.

A boundary element approach is developed for problems of hot fluid-structure interaction. The structure is idealized as a thermoelastic solid, and a time-domain, boundary-only integral formulation is described. Meanwhile, several approaches are discussed for the hot : G.

Introduction. The computation of fully coupled fluid flows with structural interactions is a rapidly evolving discipline that has been given increased attention in recent years,,.Traditional fluid flow solutions are obtained by assuming a given motion of the structure that bounds the fluid; and structural solutions are typically obtained by prescribing properties Cited by: Development of an integrated BEM approach for hot fluid structure interaction: annual report Author: Gary F Dargush ; P K Banerjee ; Y Shi ; United States.
The coupled problem is solved using a coupled BEM and FEM in-house solver. The tank structure is modeled by FEM and the liquid sloshing in the fluid domain is described by BEM. The method relies on determining the fluid pressure from the system of singular integral equations.
