摘要
利用摄相法研究了二维气-液—固三相流化床中气泡的大小及上升速度,分析了操作条件的变化对气泡行为的影响,提出了气泡直径及气泡上升速度的经验关联式.
Bubble size and bubble rising velocity in a gas-liquid-solid two-dimensional fluidized bed were studied by a photographic method.The effects of operating conditions were analysed, and correlations of bubble diameter and bubble rising velocity were presented.
