Abstract

The turbulence structures within and above a corn canopy using large eddy simulations (LES), were investigated. The computational results were compared with a recent field experiment data set from Particle Image Velocimetry (PIV) measurements and two other previous field measurements. The predictions of the mean streamwise velocity profiles by both local- and global-scale approaches agree with experimental data quite well. The wall stress was neglegible compared to that at the canopy top, indicating that the horizontal momentum was totally absorbed by the canopy.
