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 can experience icing when encountering a cloud that contains supercooled water droplets, Ice accretion is a common phenomenon in flight.Investigation on icing mechanism and effects is the basis of anti-ice/de-ice equipment design.In order to understand ice accretion deeply, the ice accretion and anti-ice/de-ice process of two-dimensional airfoil are investigated systematically by numerical simulation methods.The ice accretion process of airfoil is simulated according to messinger model and the thermal power required by the anti-ice system is calculated on the basis of this model.At the same time, a simulation of melting process on airfoil is presented respectively.
