| 摘 要： | 为了精确描述旋转床填料内的温度分布关系，文中对旋转床的径向温度分布进行了实验测定，结果发现：在实验范围内，旋转床填料内的径向温度分布与转子的转速有关，与液体流量有关，但气体流量的变化对温度分布的影响很小。文中推导出传热系数公式，并结合实验数据计算出传热系数，有力地证明了传热端效应的存在。

| Abstract: | The radial temperature distributions in the packing of Rotating Packed Bed (RPB) were experimentally investigated. The results reveal that the radial temperature distribution is related with the rotor speed and the liquid flow, but the influence of the gas flow is very little. On the basis of calculation and analysis of the radial heat-transfer coefficients, the end effect of heat-transfer is proposed. |
