| 摘 要： | 结冰问题严重威胁现代飞行器的飞行安全。当前,数值模拟结冰过程是一种高效的结冰问题研究方法。本文首先对OAXXX翼型生成六面体计算网格,然后对该翼型的流场、水滴撞击、结冰过程进行了数值模拟研究,重点研究了不同的MVD(平均水滴直径)对于水滴收集效率、冰形的影响,并将不同MVD情况下结冰后的翼型气动特性和结冰前进行了对比。

| Abstract: | The ice accretion threats the flight safety terribly.Today,the numerical simulation is an efficient method of ice accretion study. In this paper,the hexahedron mesh of OAXXX airfoil is generated,then the flow field,water droplet collection and ice accretion is simulated.It is the important face of the MVD effects on the water droplet collection efficiency and ice shapes.Then aerodynamics performances of iced airfoil for different MVD are compared with the clean one. |
