The pipeline flow of capsules: Part 8: An experimental investigation of the transport in oil of single, denser‐than‐oil, spherical and cylindrical capsules

Abstract

Abstract In the present paper, the flow behavior of single capsules of regular shape transported by two mineral oils of kinematic viscosities 45 and 7 centistokes respectively, in a 1 1/4‐inch diameter pipeline, are reported. In terms of pipe Reynolds number this means that the data for the more viscous oil were obtained for the laminar flow regime and the data for the less viscous oil were obtained, for the most part, for turbulent flow. A specific gravity range of 1.19‐7.86, a capsule diameter/pipe diameter ratio range of 0.39 (0.40)‐0.89 (0.90) and in the case of cylinders, lengths of 2‐in., 4‐in., and 7‐in. were investigated.
