摘要：

选择欧拉多相流模型和非平衡沸腾模型，用Fluent 软件对单边受热竖直向上平滑管进行了过冷流动沸腾换热的数值分析。研究了不同质量流速、进口温度和热流密度对对流换热系数和空泡份额的影响，并分析了它们对传热恶化的影响。

关键词: 过冷流动沸腾, 单边受热, 对流换热系数, 空泡份额

Abstract:

By using Fluent software with the Eulerian multiphase model and Non-equilibrium boiling model, the subcooled flow boiling heat transfers was numerically simulated in the plain upward vertical tubes under the condition of one-side heating. The influences of the different mass flux, inlet temperatures and heat flux on the heat transfer coefficient, the void fraction and heat transfer deterioration were investigated.

Key words: Subcooled flow boiling, One-side heating, Heat transfer coefficient, Void fraction
