Webwhere α=1.25643, ν is the kinematic viscosity, ζ is the wake age, and δ is a core spread eddy viscosity parameter. Additional details and models are found in Shaler et al. ().. The circulation along the blade span is computed using a lift-coefficient-based method. This method determines the circulation within a nonlinear iterative solver that utilizes the polar … WebWorth experiments, the wake vortex decay rates can be predicted better than wake vortex locations. The eddy dissipation level in the atmospheric turbulent boundary layer is a more stable quantity than the wind direction. He recommended that a warning of wake vortex circulation intensity above background should be incorporated in the FAA Integrated
