Abstract:
In this paper, a new canopy simulation method is used for the analysis of the canopy drag. The comparation between the common and new canopy simulation method is made to obtained the different influence from their simulation results. Firstly, a brief description of the simplified method of the common and the new canopy simulation methods is given in this paper. Secondly, two simplified models are made by using the new canopy simulation method and then compared with a case made by the common canopy simulation method. After the analysis of the simulations, it is found that by using the new canopy simulation method, it is managed to set the real LAD distribution along the canopy height direction, and then a more reasonable wind field data can be obtained.
