摘　　要：本文采用作者在1987年发展的大涡模拟代数模型,对弯曲槽道内的湍流运动进行了计算,结果表明该模型反映了曲率的影响,总体上与实验结果相符,说明本模型是合理的,可作为进一步研究湍流运动的手段。In the present paper the turbulent flow in a curved channel is numerically simulated by means of algebraic modelling of large eddy simulation (LES), which was developed in 1987 by the Author. The results show that this modelling can reflect the influence of the curvature and agree verywell with experimental results. These facts show that this modelling is practical and can be used as a method in further investigating of the turbulent flow. ,
