飞机积冰是飞机在积冰气象条件下飞行时,大气中的液态水在部件表面冻结并积聚成冰的一种物理过程。开展飞机积冰研究,可以使人们更深入地认识积冰产生的机理,为飞机防/除冰装置的设计提供理论基础。采用数值模拟的手段,对二维翼型的结冰过程和防/除冰过程进行了系统的研究。根据经典Messinger模型对机翼的积冰过程进行了模拟,并在此模型的基础上计算了所需要的防冰热功率,同时采用焓方法对飞机机翼的融冰过程进行了模拟。
Aircraft ice accretion is a physical process by which the liquid water in the atmosphere freezes and accumulates into ice on the part surface when the aircraft is flying under ice accretion conditions. Carrying out research on aircraft ice accumulation can make people understand the mechanism of ice accumulation in depth and provide a theoretical basis for the design of aircraft anti-deicing devices. By means of numerical simulation, the two-dimensional airfoil icing process and anti-deicing process were studied systematically. Based on the classical Messinger model, the wing ice accretion process is simulated. Based on this model, the required ice-proof heating power is calculated, and the ice melting process of the aircraft wing is simulated by enthalpy method.
