在一可同时测定轴向与径向温度分布的壁冷式固定床实验装置上 ,通过实验测定了球形、圆柱形和环柱形填充颗粒的径向有效导热系数和壁给热系数 .采用计及内、外环外表面积的颗粒等比表面积当量直径 ,将这些传热参数与Reynolds数相关联 . In a wall-cooled fixed-bed experimental apparatus capable of simultaneous determination of the axial and radial temperature distributions, the radial effective thermal conductivity and wall heat-transfer coefficient of spherical, cylindrical and annular packed particles were experimentally determined. And inner and outer ring surface area of ​​the particles such as the equivalent surface area equivalent diameter, these heat transfer parameters and Reynolds number associated.
