基于模块化思想,在FLUENT软件基础之上开发了发动机进口支板的结冰计算程序,针对尾部可调支板的结冰问题进行了计算研究。通过分析发动机进口支板结冰的物理过程,将支板结冰计算分成四个模块,分别为两相流流场计算、水滴收集计算、热力学分析和表面结冰量计算、动网格计算。首先将各模块单独进行研究,通过FLUENT提供的UDF函数及宏函数逐一实现各模块功能,最后将各模块整合,实现了发动机进口支板的结冰计算。通过计算获得了调整角度为30°时,支板的液态水含量分布、不同时间下支板结冰的区域以及不同温度下支板结冰的特点,给出了可调支板应重点防冰区域。数值模拟方法为工程应用提供了一条可选的途径。 Based on the idea of ​​modularization, an icing calculation program of the engine inlet support was developed based on FLUENT software. The calculation of the icing problem of tail adjustable support was carried out. By analyzing the physical process of engine icing, the icing calculation is divided into four modules, which are flow field calculation, water droplet collection, thermodynamic analysis, surface icing calculation and dynamic grid calculation respectively. First of all, each module is researched separately. The UDF function and macro function provided by FLUENT are used to realize the function of each module one by one. Finally, the modules are integrated to realize the icing calculation of engine inlet support. Through the calculation, the distribution of the liquid water content of the support is obtained when the adjustment angle is 30 °, the area of ​​icing at different time and the icing of support at different temperatures are given. The adjustable support should be focused on anti-icing area. Numerical simulation methods provide an alternative approach to engineering applications.
