Abstract

Numerical simulation of aircraft's wake turbulence was carried out by integrating lidar measurements. Four-dimensional variational method (4D-Var) was applied to integrate the lidar measurements into three-dimensional large eddy simulation (LES). This paper describes the results using lidar measurements at Sendai airport.
