摘要:
为了观察三维摆动水翼运动时表面压力的分布以及对流场域的影响,以NACA翼型和展弦比为1.5的NACA0012翼型为算例,采用计算流体力学方法分析了摆动水翼的水动力特性。为了提高网格质量,计算域被分为包含摆动水翼的运动域、包含摆动水翼的尾流场域以及除此之外的静止域3部分,并采用不同的网格划分条件对其进行离散,离散方程采用k-ω湍流模型求解,静止域和流体域之间采用重叠网格方法实现模拟,并利用交界面技术实现数据传递。分析了不同斯特罗哈尔数(St)条件下摆动水翼所受的推力、升力和力矩,研究了流场中速度以及压力分布,通过数值结果分析尾涡产生的机理。
Abstract:
In order to observe the distribution of surface pressure and influence of the convection field in the three-dimensional oscillating hydrofoil movement, taking the NACA0012 airfoil with the NACA airfoil and the aspect ratio of 1.5 as an example, the hydrodynamic characteristics of the swinging hydrofoil were analyzed by computational fluid dynamics. In order to improve the mesh quality, the computational field was divided into the motion field containing the flapping foil, the wake field containing the flapping hydrofoil and the rest field other than the former two fields. These three parts were dispersed under different grid partitioning condition. Solve the discrete equation by k-ω turbulence model, apply the overlapping grid method to simulate the static domain and fluid domain, and use the interface technology to realize data transmission. Analyze the thrust, lift and moment of the oscillating hydrofoil under different St number condition, study the velocity and pressure distribution in the flow field, and analyze the mechanism generating wake vortex by numerical results.
