Experimental equitions on the relation between the gas holdup of an individul channel and gas rate in either riser have been obtained by processing experimental data.
对实验数据进行回归处理得到了各区气含率与两上升区气速的经验关系式。
A drift flux model and an energy dissipation model were set up and were used to describe the gas holdup in the riser and the circulating liquid velocity, respectively.
分别用“漂流通量模型”和“能量耗散模型”描述了气含率和循环液速的变化情况。
The average relative error of gas holdup of the riser between calculated values and experimental values was 6.429%.
上升室气含率的模型计算值和试验值的平均相对误差为6.429%。
The gas holdup of the riser decreased obviously with the increasing of the solid loading.
上升室的气含率均随固体装载量增加而降低。
