The focus of the exascale wind project is to develop new simulation capabilities to improve our understanding of the performance of whole wind plants. The principal hurdle to reducing the cost of wind energy is rooted in our inability to predict the complex flow physics in wind farms.
A fully blade-resolved model of a single wind turbine would require the full computing capability of today's fastest computers. Detailed models of entire wind plants are beyond our current capabilities.
Simulating the entire wind plant fluid-structure-system on an exascale platform will drive innovation and improvements in the blade, turbine, and wind plant design and optimization processes by providing new knowledge at fidelity that is unattainable in field measurement campaigns. These simulations will complement and bridge the fidelity gaps in field experiments.
Validated high-fidelity wind plant exascale simulations will provide new insights into wind plant performance, lower the cost of wind energy, and serve as a "ground truth" foundation for new models in computer-aided engineering, wind plant siting, operational controls, and reliably integrating wind energy into the grid.
