摘　　要：本文研究了结冰数值模拟基本过程,开展了结冰数值模拟方法的验证,然后利用结冰数值模拟结果作为样本数据库,建立了冰形快速预测降阶模型,完成了二维结冰冰形快速预测。并成功将此方法应用于三维模型冰形预测,通过算例验证发现降阶模型对于结冰冰形预测与数值模拟结果吻合较好,表明降阶模型可以快速、精确的应用于结冰冰形预测。In this study we analyzed the basic process of numerical simulation of icing,carried out verification of the numerical simulation method of icing,established a reduced model for fast icing shape prediction by using the numerical simulation results as the sample database,and completed the fast prediction of the two-dimensional icing shape.This method was successfully applied to the prediction of the three-dimensional icing shape.It was found that the reduced model for icing shape prediction was in good agreement with the numerical simulation results,indicating that the reduced model could be applied to fast and accurate icing shape prediction.
