在二维流化床中，用摄像法研究了锥形分布板上射流。实验中发现，锥形分布板上射流可分为I类射流和II类射流，60°分布板上射流都是I类射流，45°分布板上观察到了II类射流，随着条件的变化射流类型也发生了改变。射流的类型与分布板角度、孔速、颗粒性质、孔的位置有关。相同气速下，0°（水平）分布板上的射流深度要大于45°和60°分布板。床层高度对射流深度的影响可以忽略。对实验数据进行拟合得到了锥形分布板上单孔射流深度关联式。

Jet penetration length on the inclined distributor was study using a video camera in a two dimensional fluidized bed. Jet profiles found in this study can be classified into two types:type I jet and type II jet. All the jets were type I jet on 60 ° distributor. Type II jet was observed on 45 ° distributor. The type of jet might change when the experimental condition was varied. Jet profile was affected by angle of distributor, orifice velocity, and property of particle and position of the orifice. Jet penetration length on 0 ° distributor was longer than that on 45 ° distributor and 60 ° distributor. The effect of bed height on jet penetration length could be ignored. A correlation is derived for jet penetration length of single orifice on inclined distributor based on the former correlation for inclined jet penetration length.
