描述了一种用于预测氧化蒸汽射流在熔融钠中的峰值温度的模型。本文作者先前的实验和理论工作表明，一个单一的、有代表性的液滴尺寸可以用来模拟水下射流中液滴与气体的热和质量交换，并且通过假设水下射流的行为类似于平面射流的空气射流雾化器来建议适当的液滴尺寸。利用这些发现，本文建立了一个合理的、完整的双流体模型，用于描述携带夹带钠滴和燃烧产物的浸没蒸汽射流内的中心线温度。得到了与钠中蒸汽射流的峰值中心线温度的合理一致的结果。
A model for predicting the peak temperature within an oxidizer-steam jet submerged in molten sodium is described. Previous experimental and theoretical work by the present authors has shown that a single, representative droplet size may be used to model droplet-to-gas heat and mass exchange within a submerged jet and that the appropriate droplet size is suggested by assuming that the submerged jet behaves like a plane jet airblast atomizer. These findings are exploited here to develop a rational, integral two-fluid model of the centerline temperature within the submerged steam jet carrying entrained sodium drops and products of combustion. Reasonable agreement with available measurements of the peak centerline temperature within steam-in-sodium jets is obtained.
