This project will extend the state of the art in computational fluid structure interactions by developing robust and accurate models for simulating flexible sheets in viscous flows. The analysis of fluid and structure interaction is fundamental to diverse engineering fields, from renewable energy production to biomedical engineering. In some applications, such as wheezing of the soft pallet and optimizing fluttering energy harvesters, the structure can be idealized as a flexible sheet. In extreme cases, such as navigating ships through debris cluttered coastal waters, these sheets are highly flexible and interact directly with one another in a turbulent flow.

The project will consist of two phases: first, a series of physics-based methods will be developed and tested to directly simulate the interaction of a well-mixed fluid with flexible sheets. The longterm goal is to use the results of these first-principle simulations to develop approximate constitutive relations for masses of interacting sheets for use in larger-scale engineering systems.

Cartesian-grid methods have been shown to be well suited to immerse the multiple dynamic solid bodies into the fluid domain, and will be employed in this project. Embedded interface methods will be used to determine the structural response to the computed fluid forces. The combination of these methods will allow the sheets themselves to be represented by simple point-cloud datastructures, enabling new methods to be developed to simulate the contact forces between sheets as they interact.
