摘要: 介绍了大涡模拟的基本原理,子网格模型,并用该方法对弯曲方管中充分发展湍流运动进行了数值模拟,与其它数值预测进行了比较,并且对湍流的部分结构进行了讨论.

关键词: 充分发展湍流, 弯曲方管, 大涡模拟

Abstract: The basic principl of LES and SGS modelling is described. This method is used to simulate the fully-developed turbulent flow in a curved square duct numerically. Its results are compared with other numerical prediction. The structures in turbulent flow are disccused.

Key words: fully-developed turbulent flow, curved square duct, large eddy simulation
