摘　　要：翼型结冰计算是随着结冰时间步长变化的准定常过程,因此在每个时间步长后都要更新各个模块的计算工作,如此反复直到达总结冰计算时间.在各模块计算中,分别采用了泊松方程法生成网格、求解雷诺时均方程计算流场、拉格朗日追踪法求解水滴轨迹、基于Messinger模型计算冰形、采用变距滤点法重构边界.引入动态链接库技术将各模块集成为结冰计算平台,并将三种冰形(楔形冰、槽状冰及混合冰)计算结果与国外软件及试验数据进行了对比.The computational procedure for ice accretion is an iterative process.The overall calculation of ice simulation at each time-step involves five main parts： generating grid using Poisson equations,calculating flowfield by solving Navier-Stokes equation,calculating particle trajectory,thermodynamic analysis and ice accretion calculation,reconstruction of the ice boundary.The code is modular and contains six separate program elements including plot results.At last,the results calculated using the present software were compared to numerical and experimental data presented in American Institute of Aeronatutics and Astronautics（AIAA） papers,with ice shapes containing rime-ice,glaze-ice and mixed-ice.
