振动流化床水平换热管的传热系数随颗粒粒径的增大而减小。
It is also found that the local heat transfer coefficients of horizontal tube exhibit a general tendency to increase with decreasing particle size.
在操作气速0.1ms-1、振幅2mm及振动频率1100min-1的条件下，振动流化床水平换热管的传热系数达到最大值。
The results show that heat transfer coefficient reaches maximum value under the condition of gas velocity of 0.1ms-1, vibration amplitude of 2mm and frequency of 1100min-1.
