Simulation of Atmospheric Boundary Layer Flows
Accurately simulating atmospheric boundary layer flows is challenging because of their complex, multi-scale turbulence, limiting the reliability of wind predictions used in applications such as wind-energy planning and turbine design. CEEC used extreme-scale computing to perform high-resolution simulations with up to 100 billion grid points, providing more detailed atmospheric-flow information that could support improved wind-resource…

Localized Erosion of an Offshore Wind-Turbine Foundation
Uncertainty in suction bucket installation can increase the risk of localized soil erosion and foundation failure, with potential consequences for installation time and offshore wind project costs. Using HPC-powered, grain-scale fluid–soil simulations, CEEC improved the accuracy of engineering models for predicting erosion and suction behaviour, helping reduce installation uncertainty and support more cost-efficient foundation installation.…

High Fidelity Aeroelastic Simulation of the SFB 401 Wing in Flight Conditions
Uncertainty in aeroelastic predictions forces aircraft manufacturers to rely on conservative design margins, increasing weight and certification costs. Using exascale fluid–structure simulations, CEEC demonstrated how high-fidelity modelling can improve load prediction, reduce development risk, and support more efficient aircraft designs.
