Large eddy simulation of a utility-scale horizontal axis turbine with woody debris accumulation under live bed conditions
Published in Renewable Energy, 2025
In this study, we conduct high-fidelity large-eddy simulations (LES) to examine the performance and environmental impact of a utility-scale horizontal axis turbine operating under live bed conditions with woody debris accumulation. We analyze the complex interactions between the turbine, sediment transport, and flow structures when large debris is introduced into the system. The results reveal significant alterations in wake dynamics, bed shear stress distribution, and power production. These insights are critical for improving the resilience and design of hydrokinetic systems deployed in natural, sediment-rich environments.
