THIS GRANT IS A CONITINUATION OF N000141410367 High-fidelity simulations of fluid-structure interaction for leatherback sea turtle inspired propulsion
Abstract
Funds are provided to perform the following tasks: (1) Develop a 3D Spectral Difference code for incompressible flow to deal with moving and deformable grids from the 2D baseline code that is parallelized using Message Passing Interfaces (MPI) for cross-processor communication and ParMetis for automatic domain decomposition. (2) Develop a 3D FEM code using unstructured meshes to solve the large amplitude deformation of turtle limbs. Active stress will be incorporated into the finite elements. (3) Integrate both fluid and structure solvers with high-order accurate representation at fluid-structure interfaces through development of a new computational framework using high-order discretization methods for both fluid and structure with unstructured meshes. (4) Validate this computational framework for fluid-structure interaction using existing benchmark test problems. Subsequently, perform large-scale computations for high-fidelity simulations of turtle-inspired underwater vehicles.
