Two-phase flow in a coiled tube: Pressure Drop, Holdup, and Liquid Phase Axial Mixing

Abstract

Data on pressure drop, holdup, and axial liquid mixing are reported for two-phase concurrent flow in a 1/2-inch diameter spiral tube. The over-all objective of this study was to obtain scale-up data and correlations for a two-phase flow spiral reactor. Pressure drop and liquid holdup data have been compared to known correlations and a new correlation based on a gas drag coefficient is presented. Liquid holdups were measured by a “tracer” method in addition to the more conventional method of trapping. The tracer technique also permitted measurement of the axial mixing in the liquid phase. © 1966, American Chemical Society. All rights reserved.
