| 摘 要： | 采用时变雷诺方程结合κ-ε湍流模型,模拟探头在下沉过程中的运动状态。根据模拟所得探头附近速度与压力分布,积分出阻力系数,由此分析阻力系数随雷诺数变化规律。同时进行物理实验,并与数值结果比较,二者吻合较好。

| Abstract: | A numerical model,based on Reynolds equations and turbulent model,was developed to simulate the moving status of a probe descending through the sea.According to the estimated flow and pressure field near the probe,the drag coefficient was integrated and its relationship with Re was analyzed.Experiments were conducted for verification of the calculations. |
