后台阶流动的大涡模拟
Large eddy simulation in backstep flow
-
摘要: 利用大涡流模拟,对后台阶中的流动进行了数值计算,并和实验数据进行了比较,吻合较好,表明了所采取的亚网格湍流模型的合理性,但是需要改进.Abstract: Simulation of backstep flow is carried out using large eddy simulation,and comparison with experiment data is performed.The better result shows that the SGS model is effective,but need to be improved.
