The effects of rotational speed and open-hole size of two kinds of distributing devices were analyzed. The results showed that:1There are two kinds of flow patterns for the two distributing devices,i.e.,plug flow and funnel flow;2particle mass fluxes increased non-linearly with the increase of rotational speed and open-hole size of the distributing devices;3along the radial direction,particles were distributed more uniformly with increasing the rotational speed and open-hole size,and the distribution showed U and M shapes for the two kinds of distributing devices;4the radial distribution of particles were more uniformly downwardly along the axial direction,with values of the variance coefficient exceeding 1.0 for the fan-shaped hole distributing plate,and 0.5 for another distributing plate.Read More
