| Abstract(in English) | A flying aircraft generates a coherent vortex pair due to its lift and a turbulent flow including the vortex pair is called wake turbulence. A following aircraft is affected by wake turbulence of a leading aircraft, therefore, wake turbulence separation is defined based on the sizes of those aircraft. In this report, we describe basic characteristics of wake turbulence. The dynamics of wake turbulence from the generation until vortex decay are then explained with the help of large eddy simulation results. We especially emphasize that vortex decay occurs due to vortex linking or the interaction with the ground, where secondary vortices play an important role on the decay. We also mention lidar measurements of wake turbulence. |
