Particle movements on louver supporting moving granular bed

Abstract Movement of particles on a louver element which supports particles in a moving bed was investigated using several types of louvers. For smooth movement of particles on the louver element, it was found effective to utilize a double-element type louver consisting of a main louver element and a sub-louver element. An optimal inclination angle of the sub-louver to the horizontal line existed, and this value could be predicted by applying the plane stress state to the packed bed of particles adjacent to the sub-louver element. The measured stresses on the sub-louver were in good agreement with those predicted by the same theory.
