飞机地面结霜机理及分阶段预测模型
Mechanism of aircraft ground frosting and staged prediction model
摘要
Abstract
Aircraft ground frost has an impact on flight safety and causes flight delays.An accurate frost forecast is an essential basis for the generation of airport snow removal parameters.Frost formation on aircraft ground is influenced by many factors such as weather,body surface structure and flight time,and airports have special forecast indexes for aircraft frost formation.Therefore,frost formation on aircraft ground is divided into the nucleation stage and the frost layer growth stage.A frost formation temperature model based on classical nucleation theory is established during the nucleation stage,and the frost formation temperature is defined as the temperature at which the coverage rate of frozen liquid nuclei approaches the threshold.The surface characteristics of aircraft and the influence of the external environment on the frosting temperature were studied.During the growth stage,the Euler multiphase flow-based frost layer growth model is developed,the frost layer growth identification criterion is added from the frost layer formation principle,and the impact of various working conditions on the frost layer properties of the aircraft surface is investigated.The results of simulation and field experiments show that the average error of the frost formation temperature model is 0.65℃.The average error of the frost growth model is 5.99%.The results demonstrate that the proposed phased modeling method can provide theoretical support for predicting ground aircraft frosting.关键词
