The magnitude of the maximum value, as well as the time to reach such maximum value, varies with geometry and surface heat-transfer coefficient.
最大值的及达到此最大值的时间均随几何形状和表面热传导系数而变。
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.
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。
