摘要：

An extensive investigation was made of the particle dynamics of narrow spherical glass beads transported vertically by a turbulent air stream in a 10-cm. i.d. pipe. The particle axial velocity profile in the pipe core region was found to be similar to that of the gas and to follow a power-law type relationship. Within the range investigated the slip velocity at the center of the pipe is a function of the loading ratio and the particle terminal velocity, the particle concentration is uniform across the pipe cross section, and particle velocity fluctuations follow the pattern of the free stream turbulence of the gas phase. © 1969, American Chemical Society.
