| 本文基于分区多块结构网格体系,采用欧拉方法建立过冷水滴控制方程,通过有限体积方法对方程进行求解,发展了适合三维复杂外形的水滴撞击特性计算方法和计算程序。通过单段翼型、多段翼型等算例对该方法的验证计算表明,在常规尺寸水滴算例中,水滴撞击特性计算结果与国外标准模型试验数据吻合良好。在此基础上,开展了三维高升力机翼水滴撞击特性数值模拟研究,分析表明计算结果合理,可用于飞机防除冰系统设计。 |
| 英文摘要: |
| Base on the multiblock structured grid strategy, the motion equation of supercooled water droplet was established by the Euler method. A finite volume method was used to solve the motion equation. A droplet impingement calculation method and the simulating program for 3D complex configuration of airplan were developed. Some cases include 2D airfoil, multi-element airfoil are used to validate the program. The computational results are in good agreement with the experimental data. Then the water droplet impingement characteristics on a 3-D highlift wing were calculated. The computational results show the method and program can be used the tools to design anti/deicing system of airplane. |
