| 摘 要： | 为了分析钠盐气溶胶的形成机理,有必要对加热圆管内的温度场进行研究。本文从理论上导出了加热管内的简化温度场并根据实验条件确定了管内流体的流态。在此基础上,分别讨论了温度边界层、主流区、充分发展区三个区间内温度场分布的特点,提出了一种计算边界层区间内温度场分布的新方法,为圆管内液滴群蒸发衰减的进一步研究奠定了基础。

| Abstract: | In order to analyze the formation mechanism of sodium chloride aerosol,it is indispensable that the temperature filed in heating tube was researched.The simplified temperature filed was educed on theory and the flow form was confirmed based on experimental conditions.On this foundation,the feature of temperature distribution was discussed respectively about boundary layer,major area and full development area in heating tube,and a new method to calculate the temperature distribution was raised in boundary layer,which was propitious to investigate the decay of liquid droplets group in circular pipe. |
