The influences of the superficial gas velocity, solid holdup and flowing resistance on gas holdup, bubble size, bubblerisevelocity 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。
2
It can be neglected that risevelocity 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。
3
A model for the risevelocity of a single deformed bubble in liquid solid fluidized beds was formulated, based on the analysis of the forces acting on a bubble.
