【摘要】 蒸汽蓄热器内部充热过程是蒸汽与水两相流体强烈地混合，传热与传质的复杂过程。本文建立了启动过程中水空间温度场分布规律的数学表达式，并绘制了热水循环流动的流线，较正确地反映了蒸汽蓄热器内部温度场的分布规律。更多还原

【Abstract】 Abstract Virulent mixing of a steam-water two phase flow takes place in a steamheat reservoir during its storing process accompanied by complex heat andmass transfer.A mathematical expression is proposed in this paper for thetemperature distribution of the water filled space during starting and a streamline picture of the circulating hot water is shown,which more accurately reflectthe temperature distribution within a steam heat reservoir.更多还原
