Abstract

This paper presents a three-dimensional (3D) numerical study of the unstable motion of horizontal solitary and consecutive slug flows by means of discrete particle simulation. The proposed model is quantitatively verified by comparing the calculated and measured results in terms of particle velocity, slug velocity, and stationary layer thickness. The results show the startup of slug flow can be neglected, and the collapse of a slug leads to the integration of two slugs. Particles pile up at the pipe bottom of particle-feeding region and are transported away as a slug when the resultant pressure builds up high enough. In a consecutive slug flow, the pressures along various slugs in a horizontal pipe drop at a same rate regardless their positions. The results are consistent with experiments.
