Geldart groups A (NiO – 1300 μm, green), B (MoO₃ - 480 μm, white), and C (NiO – 30 μm, gray color and MoS₂ – 25 μm, black) particles were used in a transparent, acrylic fluidized bed reactor. The experiment was carried out for four cases by setting the position of the particles injected in the reactor as a variable. For these cases, Geldart group C particles (which are typically difficult to fluidize) were included. When easily fluidizable particles were placed at the bottom of the fluidized bed reactor, particle circulation and bubbling occurred. Channeling occurred when there were particles that were difficult to fluidize. Homogeneous fluidization was possible with vibration when channeling occurred. With the increasing vibration frequency, the pressure drop increased, and the minimum fluidization velocity decreased. The occurrence of channeling via vibration resulted in a high mixing index and variations in the pressure drop.

Geldart组A（NiO – 1300μm，绿色），B（MoO ₃ – 480μm，白色）和C（NiO – 30μm，灰色和MoS _2）–在透明的丙烯酸流化床反应器中使用了25μm黑色颗粒）。通过将注入反应器中的颗粒的位置设置为变量来进行四种情况的实验。对于这些情况，包括了Geldart C组颗粒（通常难以流化）。当容易流化的颗粒置于流化床反应器的底部时，发生颗粒循环和鼓泡。当存在难以流化的颗粒时发生通道化。发生窜流时，通过振动均质流化是可能的。随着振动频率的增加，压降增加，最小流化速度降低。经由振动的窜动的出现导致高混合指数和压降的变化。
