摘要：
The apparent overall heat transfer coefficient between column wall and bed for gas-liquid-solid systems was measured over a wide flow range from packed to fluidized bed, and the effects of column diameter gas velocity, liquid velocity, height of heat-transfer section, properties of solid particles and liquid viscosity were studied. When water was used as liquid phase in the tower of 0. 12 m i. d. , as liquid velocity increased at constant gas velocity, the heat transfer coefficient first increased, reached a maximum, then decreased to a minimum and again increased rapidly.
