Incorporating the two-phase model of air-supercooled droplets in the Eulerian coordinates,this technique was applied to simulating the process of the rime ice accretion (the droplets freeze at the instant impinging on the airfoil) on the NACA 0012 airfoil,and the ice profile after ice accretion was achieved successfully.
提出了一种处理结冰后结冰表面固壁区域移动的移动边界技术,结合欧拉坐标系下空气-过冷水滴两相流动控制方程的计算,对霜状冰的结冰过程进行了数值模拟,得到了NACA0012机翼在0°和4°攻角下机翼表面结冰后形成的冰形,与文献中的实验数据对比,表明本文的方法是可行和有效的。
