The results showed that the flow reattachment distance in the lee side of various dune models are ranged from 4.8H to 10.8H depending on different stoss slopes, the maximum of flow reattachment distance was found in the lee side of the transverse dune with a 15° stoss slope angle.
实验结果表明,当来流风速垂直于沙丘脊线时,沙丘背风侧的气流重附距离介于4.8H~10.8H之间,最大重附距离出现在迎风坡坡度为15 的沙丘背风侧;沙丘迎风坡坡度是控制背风侧气流重附距离的主要因素,而自由风速对气流重附距离的控制作用较小。
