摘要：

Experimental results are presented on fundamental particle mixing phenomena in a bed of granular material agitated by a moving blade in a two-dimensional vessel. The study is the first step aimed at evaluating the dryer wall-to-particle heat transfer coefficient for drying operations from knowledge of fundamental particle mixing. The parametric effects of the height of the blade, bed depth and blade velocity for a fixed clearance between the wall and the blade are discussed for a bed of glass beads. It was found that the ratio of the bed to blade height might be more important than the blade speed in influencing movements within the bed.
