摘要(Abstract)：

燃气轮机正常运行需要大量的空气进给，而进气系统结冰会导致燃气轮机运行效率降低，因而保证进气系统性能稳定性对于燃气轮机至关重要。实验利用ANSYS的Fluent模块，对燃气轮机进气系统易结冰位置的内部流场进行数值模拟仿真。模拟结果表明，进气温度在265 K时，水蒸气会在滤网处大量聚集，为结冰创造了初始条件；另外，进气温度265 K压降比300 K的压降高150 Pa，这进一步为结冰创造了有利的条件。同时过滤器处进气速度和温度呈现反相关关系，这解释了燃气机在冰点温度以上工作时，过滤器处仍旧存在结冰的原因。这些计算结果为低温环境下燃气轮机进气系统防冰以及提高燃气轮机工作效率提供参考。
