| 摘 要： | 本文建立了被水饱和的一维多孔介质中一端注入蒸汽后液区温度分布的数学模型，导出了向半无限大侧向介质散热的热流密度项，以及以凝结前缘运动速度表示的控制方程对流项系数的具体表达式，考虑了水蒸汽凝结前缘这一移动边界条件，提出了运用拉氏变换及数值反演求解此问题的一种计算方法，获得的计算值与实验结果一致。

| Abstract: | On the basis of the physical model for steam condensing flow in 1-dim porous media ininial-ly saturated with water, the temperature distribution in the hot liquid zone is described by an integro-diferential equation.The integral representation of the lateral heat losses and an expression of the coef-ficient of convection term are derived. an algorithm to solve the equation by use of Laplace transformin proposed.The numerical results anr in agreement with the experimental results. |
