โœฆ Synopsis

Slug flow was studied for air velocities less than 8 m/s with polyethylene pellets in a straight pipe 32 mm in diameter and 5.5 m in length, and was classified into 2 regimes: successive slug flow and solitary slug flow. A settled layer of particles did not form in the latter and high air pressure was required to push the slug as compared with the former. Successive slug flow was found in the low-velocity region where the power consumption reaches a minimum, a minimum that is lower than the minimum of the suspension flow region.

First, the characteristics of low-velocity conveying of particles having different hardness are experimentally investigated in a horizontal pipeline in terms of flow pattern and pressure drop to show that the slug flow can be classified into two types depending on the settling of particles along the

Current relationships for determination of the pressure drop with pneumatic conveying of solids in pipes are not of general validity. The theoretical considerations underlying these relationships do not take into account the influence of the rotatory motion of the particles. On the other hand, extre
