摘　　要：在空泡水筒内进行水翼模型试验时,水翼模型的水动力性能会受到筒壁的影响。为此,以NACA0009水翼为研究对象,基于Realizable k-ε湍流模型,采用计算流体力学软件STAR-CCM+对二维水翼的水动力性能进行计算。通过将计算结果与模型试验结果相对比,验证该计算方法的准确性。同时,系统地分析不同阻塞系数(λ)下水翼的升力系数(C_(L))和阻力系数(C_(D))的变化特点,并给出小攻角下有筒壁效应时,水翼C_(L)的计算公式。研究表明:C_(L)随着λ的增大呈指数形式减小并趋于定值,C_(D)随着λ的增大先减小后增大并趋于定值;当λ≥16.0时,C_(L)和C_(D)不受壁面效应的影响。When a hydrofoil model test is carried out in a cavitation tunnel,its hydrodynamic performance will be affected by the wall of the tunnel.The computational fluid dynamics software STAR-CCM+coupled with Realizable two-layer k-εturbulent model is used to calculate the hydrodynamic performance of two-dimensional hydrofoil within the tunnel and to find out the impact of tunnel wall.The model is verified first by means of comparative analysis with experimental data.The variation characteristics of lift and drag coefficients of hydrofoil with differentλare systematically analyzed.The results show that,with the increase ofλ,C_(L) decreases exponentially and gradually approaches a constant value,while C_(D) decreases first and then increases and finally goes saturated.Whenλ≥16.0,C_(L) and C_(D) are not affected by the wall.
