The influences of the superficial gas velocity, solid holdup and flowing resistance on gas holdup, bubble size, bubble rise velocity and liquid velocity were systematically studied.
考察了表观气速、固含率和流动阻力对气含率、气泡大小、气泡上升速度和液速的影响。
It can be neglected that rise velocity of gas bubble is very small in melt.
气泡在熔体中的上升速度很小，可以忽略。
A model for the rise velocity of a single deformed bubble in liquid solid fluidized beds was formulated, based on the analysis of the forces acting on a bubble.
以气泡在上升运动过程中的受力分析为基础，建立了描述单个变形气泡在液-固流化床中上升速度的理论模型。
