摘　　要：本文分析了采用蒸发冷却的发电机线棒空心导线内冷却介质的两相流动规律。在分析了冷却介质在单相和两相流动段的循环动力和流动阻力的基础上，建立了循环流量、流体温度分布及空心导线内壁温度分布的计算方法。为发电机定子所有方向上的传热和温度分布计算打下了基础。This paper analyzes the characteristics of two-phase flow in the evaporative cooling generator stator windings. Based on the analysis of circulating power and flowing resistance on single and two phase flow, the paper gives out the calculating methods of cycle flow rate and temperature distribution both in the coolant and inner side of hollow conductor. The results supply basis for next calculation on heat transfer and temperature distribution in evaporative cooling generator stator in every direction.
