摘要
Using particle image velocimetry (PIV) we studied experimentally the whole velocity field during the discharge of monodisperse granular material from a flat-bottomed 2D silo. We have characterized important quantities of this how such as the transversal flow oscillations, the mean velocity field and the velocity fluctuations. (C) 1998 Elsevier Science B.V.
