摘要
由于传统通风计算方法难以胜任大容量机组复杂通风系统计算,采用流体网络等效回路法与CFD数值模拟相结合的方法,对一台1100 MW核电汽轮发电机进行了通风计算,得到了整个发电机内通风冷却主要部件的流量分配。电厂实际运行证明温度满足要求。
Because the traditional ventilation calcu-lation method was hard to take charge of calculating the complex ventilation system of the turbine generator with large power capacity, the combined equivalent liquid net-work method and CFD data analogue method were applied to calculate the ventilation of a 1 100 MW nuclear power turbine generator, getting the ventilation distribution of all main parts within the generator. Its practical operation in the power plant veriifed that the temperature met with the requirement.
