摘要 为探究Fluent中更加有效的刚性植被尾流区模拟方法.基于已有试验数据,对比Fluent在模拟刚性植被时两种模拟方法(细圆柱群模型和多孔介质模型)的差异。结果表明,二维刚性植被尾流区模拟中,在待模型稳定时间可忽略不计的情况下综合前处理、模拟情况对比,多孔介质模型更加高效便捷、模拟效果更好。 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.
