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
