| 目的 获得跨音速风扇转子叶片高、低转速下混合相积冰的影响规律。方法 使用CFX获取风扇叶片空气流场数据，采用FENSAP-ICE获取积冰冰形，通过过冷水滴与冰晶温度、撞击叶片角度等进行混合相积冰高、低转速冰形分析。结果 风扇叶片高、低转速运转时，过冷水滴与冰晶的运动状态变化相对明显。高转速时，流场内的气流为跨音速流动，过冷水滴与冰晶撞击角度相差较大，撞击角度较大的叶根区域更容易收集过冷水滴与冰晶；低转速时，过冷水滴和冰晶与叶片的撞击角度大部分区域低于10°，使过冷水滴与冰晶碰撞到叶片后的捕获难度提升。风扇叶片高、低转速运转时，叶身的温度差异使过冷水滴在低转速下易直接凝结，未凝结的水膜量极少，而冰晶表面未形成水膜，不易被捕获，使得最终的积冰主要为过冷水滴积冰。结论 风扇叶片混合相积冰在高转速时，流道内温度升高更快，水膜不易凝结，冰晶表面易融化，促进了冰晶积冰。 |

| The work aims to obtain the influence of icing on the mixed phase of transonic fan blades at high and low velocities. CFX was used to obtain the airflow field data of fan blades, and FENSAP-ICE was used to obtain ice shapes. The ice shape at high and low velocities of mixed phase icing was analyzed through the temperature of supercooled droplets and ice crystals and the angle of impact on blades. The results showed that when the fan blade worked at high and low velocities, the motion states of supercooled droplets and ice crystals varied significantly. At high velocities, the airflow in the flow field was transonic flow, and the impact angle between supercooled droplets and ice crystals was different. The root area with large impact angle was easier to collect supercooled water droplets and ice crystals; at low velocities, the impact angle of supercooled droplets, ice crystals and blades was less than 10° in most areas, which made it more difficult to capture supercooled droplets and ice crystals after they collided with the blades. The temperature difference of the blade when the fan blade ran at high and low velocities made the supercooled droplets easy to condense directly at low velocities, and the amount of uncondensed water films was very small. However, the ice crystal surface was not easy to be captured because the water film was not formed, so the final ice accretion was mainly the ice accretion formed by the supercooled droplets. When the fan blade mixes phase icing at high velocities, the temperature in the flow passage rises faster, the water film is not easy to condenses, and the ice crystal surface is easy to be molten, which promotes the ice accretion of ice crystals. |
