Abstract

Correlations for the extension of a water vapor jet injected in a liquid pool were historically proposed considering the mass flux (kg/m2/s) as a constant. The results were satisfactory, however adjusting the values by linear regression. Although, it presents the following drawbacks: 1) the formulation is only valid for the specific range of data for what it was created; 2) it does not allow the analytical evaluation of the heat transfer coefficient from the extension equation. This paper proposes a new formulation for the calculation of the mass flux, in such a way to remove both of these drawbacks.
侵彻射流半经验关系式的新公式
历史上曾提出将质量通量(kg/m2/s)作为常数来考虑注入液体池中的水蒸气射流扩展的相关关系。结果令人满意,但通过线性回归调整了数值。虽然,它提出了以下缺点:1)公式只适用于特定范围的数据为它所创建的;2)它不允许从扩展方程解析计算换热系数。本文提出了一种计算质量通量的新公式,从而消除了这两个缺点。
