| 摘 要： | 采用S—A湍流模型，对一个开式二维方腔的温度场和速度场进行了数值模拟，并把模拟结果与实验值进行了比较，确认了所选湍流模型的可靠性。在此基础上对某1．5MW常温型风电机组机舱内部温度场和速度场进行数值模拟，得到了机舱内部的温度分布云图，对合理选取散热孔位钱及散热方式有一定的参考意义。

| Abstract: | The S-A model is used to simulate the temperature field and the velocity field of an opening two-dimensional rectangular space, and the simulation results are compared with the experiment data to verify the reliability of the S-A model. And then, the interior temperature field and the velocity field of a I.SMW wind turbine are calculated to obtain the temperature distribution, which could be used as guidance for the reasonable selection of the wind turbine nacelle vent and the cooling method. |
