【Abstract】 In this paper the k- δ -E turbulence model is used to derive the mathe-matic model of two-dimensional flow in trenches with arbitrary shapes. The boundary-fitted coordinate system and the finite analytic method are applied to predict the mean-flow field and the turbulent transport properties field. Two examples are calculated. The results agree closely with the experimental data.更多还原
