| Abstract: | In order to explore a more effective method for simulating wake area of rigid vegetation,based on the ex-isting experimental data,the two simulation methods(the thin cylinder group model and the porous medium model)were compared for simulating rigid vegetation by Fluent.The results show that in the simulation of the two-dimensional wake area of rigid vegetation,the method of porous media is more effective and precise with better simulation effect on the con-dition that the time to stabilize the model can be negligible. |
