Numerical study on water film flow and sheddingin ice accretion of rotating spinner

摘要

摘要: 为了更准确地模拟旋转整流罩积冰过程，在现有三维积冰与冰层表面薄水膜流动耦合模型基础上，基于功平衡分析的方法引入了旋转部件表面水膜脱离模型，并发展了相应的计算方法，给出了水膜脱离的判定依据：当气流曳力做的功和由于离心力使水膜增加的潜能之和大于黏附功时整流罩表面的水膜会发生脱离。对旋转整流罩积冰进行数值模拟，计算结果与实验结果吻合得较好，验证了该模型的合理性和计算方法的可行性。之后分析了转速和来流速度对整流罩表面水膜脱离和积冰的影响，结果表明：转速和来流速度越大，水膜发生脱离的比例越大。在研究范围内，转速为3000r/min和6000r/min时，因水膜脱离导致积冰总量分别减少13.4%和15.8%；来流速度为40、50m/s和60m/s时，因水膜脱离导致积冰总量分别减少为12.2%、13.4%、14.2%。

Abstract: In order to simulate ice accretion accurately, a water film shedding model on rotating surface was introduced with the method of work balance analysis based on the current three-dimensional coupled model of ice accretion and thin water film on ice surface. A computational methodology and a criteria of water film shedding were then presented. Water film shedding occurred when the work done by air drag force plus potential energy caused by centrifugal force was greater than adhesive work. When the method to numerical simulation of rotating spinner, the simulation results agreed well with experimental results, indicating the current model was reasonable and computational method was feasible. The effect of rotating speed and air speed on water film shedding and ice shape was also simulated. The results show that the proportion of water film shedding increased with larger rotating speed and air speed. The ice mass decreased 13.4% and 15.8% respectively due to water film shedding, when rotating speed was 3000r/min and 6000r/min.The ice mass decreased 12.2%, 13.4% and 14.2% respectively due to water film shedding, when air speed was 40m/s, 50m/s and 60m/s.
