In order to investigate the three-dimensional effects on the flow characteristics of the thin water film for the three-dimensional wings, the numerical simulation of the droplet impingement and film flow on the MS-0317 wing is implemented based on the open-source package OpenFOAM. The simulation focuses on the effects of the angle-of-attack and the angle of sweepback. The movement and impingement of the droplets are calculated using the Lagrangian method, and the film flow is simulated using the thin film assumption and the finite area method. The simulation of the water film flow of the three-dimensional MS-0317 wing shows that there is a spanwise flow of the water film due to the three-dimensional effects. This suggests that more research should be conducted on the warm glaze ice with surface water film of three-dimensional ice accretion on three-dimensional geometries.

三维机翼液滴撞击和薄膜流动的数值模拟

为了研究三维机翼薄水膜流动特性的三维效应，基于开源包对MS-0317机翼上的水滴撞击和水膜流动进行了数值模拟。打开泡沫。仿真重点关注迎角和后掠角的影响。采用拉格朗日法计算液滴的运动和撞击，并采用薄膜假设和有限面积法模拟薄膜流。对三维MS-0317机翼水膜流的模拟表明，由于三维效应，水膜存在展向流。这表明应该对三维几何上的三维冰积聚表面水膜的暖釉冰进行更多的研究。
