High-Resolution Numerical Simulations of Environmental, Renewable Energy, and Biological Flows
The Computational Hydrodynamics and Biofluids Group at the St. Anthony Falls Laboratory is developing high resolution, fluid-structure interaction computational fluid dynamics models for simulating: physiologic blood flow in mechanical heart valves implanted in patient-specific anatomies; flow past wind and hydrokinetic turbines; and turbulent flow and sediment transport in natural rivers with nature and man-made structures. The numerical algorithms employ a sharp-interface immersed boundary method for handling arbitrarily complex geometries with multiple moving immersed bodies enhanced with local grid refinement approach. Both loose and strongly coupled fluid structure interaction algorithms have been developed and validated. The computer code has been parallelized with MPI.
