Description

Innovations like the Leading Edge Tubercle on wind turbine blades improve efficiency and performance. These tubercles have little rounded edges at their leading edge, inspired by humpback whale flippers. The biomimetic design reduces turbulence and stall, allowing the blade to function in a broader wind speed range. Tubercles interrupt flow separation and reduce drag, resulting in more uniform lift distribution along the blade, boosting the capture of energy and turbine efficiency.

Given the reference paper entitled “ Leading edge tubercle on wind turbine blade to mitigate problems of stall, hysteresis, and laminar separation bubble “, CFD simulation is carried out to model the leading-edge tubercle effect on turbine blades.

Simulation Process

The wavy shape of the leading edge is designed utilizing Spaceclaim software. In the second step, Fluent Meshing software takes the lead and generates 4031516 cells over the domain. The extended domain around the blade is necessary to capture the wakes formed behind the blade. The K-omega SST turbulence model is employed because it brings benefits of K-epsilon features near the wall regions and K-omega features far behind the blade. Further, air enters with a positive angle of attack toward the blade.

 

Post-Processing

Simulating Leading Edge Tubercles on Wind Turbine Blades provides advising velocity contour visualization results. These contours show a significant velocity drop beneath the blade, where wake production occurs. Simulations show that carefully integrating tubercles along the leading edge disrupts airflow patterns, minimizing the low-velocity zone beneath the blade. This indicates that tubercles reduce turbulence and stall, optimizing airflow distribution and lowering wakes. These data suggest that this new design method might improve wind turbine efficiency by reducing wake impacts.
