To understand the interaction wake effects of aligned horizontal-axis wind turbines, a refined and low-cost simulation framework is developed by combining actuator line (AL) with local dynamic Smagorinsky (LDS) model. Firstly, published performance NREL-5MW turbine used to corroborate accuracy AL-LDS coupling Secondly, research extended predict interference between two tandem rotor wakes. The influence precone characteristics on overall power output turbines explored modifying upstream introducing latest third-generation Ω vortex identification method in post-processing procedure. According results, have complex interference, angle variation always reducing global power, leading an unstable downstream wake. This detrimental system lifespan due high fluctuation stress as well may ecological implications sediment alteration. From upwind (negative) can lead higher but lower performance, compared non-tilted turbine. Despite optimal 0°, -2.5° proves more advantageous owing large flexible deformation wingtips. findings serve continuous incentive for improving farm numerical simulation.
