An Overview of the Common Fluid Models Used in Fluid-Structure Interactions
Abstract
This report derives and discusses some of the fluid models more commonly used in fluid-structure interaction problems. The emphasis is on linearized, self-contained governing equations on the solid-fluid boundary which directly govern the fluid response of a solid structure which is interacting with an adjacent fluid. The overview given should enable such an engineer to obtain at least a cursory understanding of the origin and limitations of the fluid models which are in common use for such purposes. The report starts from a general model of fluid mechanics and moves to an acoustical medium model from which the retarded potential formulation is obtained. This then leads to the early-time, late-time, and Doubly Asymptotic Approximation models.
