摘　　要：根据在粉体中运动物体受力分析 ,对几种不同型式搅拌桨功率准数表达式进行了推导 ,并对搅拌流化床中的功率准数与通气速率和搅拌速度进行了关联 ,关联结果与实验值吻合较好。The power requirement for agitating the fluidized bed of solid particles was investigated.The power numbers of several types of agitator were introduced.The rotational speed,as well as superficial gas velocity,had been found very important for the power number.New power number correlation equations were also introduced.The correlation equations could predict the power consumption successfully.
