Abstract This paper expands on the work described in OTC 22935 (Slug Flow Induced Vibration in a Pipeline Span, a Jumper, and a Riser Section [1]). Different boundary conditions of the pipeline span, flow rates, slug lengths, and slug frequencies are investigated for slug flow induced vibration of the pipeline span ...

Characteristics of the Liquid Slug and the Taylor Bubble in a Vertical Slug Flow
Heat Transfer: Volume 5 — Numerical and Experimental Methods in Heat Transfer, 1998Abstract Measurements in vertical upward concurrent slug flows are presented. The experiments, carried with mixtures of air and water and a viscous aqueous solution, were aimed to the characterization of the structures that form the slug flow. Double-wire conductive probes were carefully designed and calibrated to identify and to measure

Film and slug behaviour in intermittent slug–annular microchannel flows
Chemical Engineering Science, 2010Abstract Whilst there are numerous experimental, theoretical and computational studies of Taylor flow in microchannels, the intermittent slug–annular regime has largely been neglected. In this paper time-resolved micro-PIV data are collected and used to study the flow characteristics of a gas–liquid system for flow regimes spanning Taylor to annular ...

Investigation of flow structures in vertical slug flow
Nuclear Engineering and Design, 1997Abstract The flow structure of gas–liquid slug flow in a vertical tube has been investigated experimentally and numerically. A photochromic dye activation method was used to obtain two-dimensional liquid velocity profiles around a Taylor Bubble rising in stagnant kerosene in a vertical 25.6 mm I.D. pipe.

Publisher Summary Slug flow is a highly complex type of flow with an unsteady nature. The prediction of pressure drop, heat, and mass transfer for such flow is often considered a difficult task. The chapter deals with steady slug flow. The chapter introduces several options of modeling the hydrodynamic parameters and pressure drop using a unified ...

Prediction of slug frequency in horizontal two‐phase slug flow
AIChE Journal, 1990AbstractAvailable data on slug frequency in horizontal two‐phase intermittent flow are predicted with adequate accuracy by assuming that the slug frequency is one half of the frequency of the unstable waves precursors of slugs, as determined according to published analyses of finite amplitude waves in conduits.

This chapter describes gas-liquid slug flow (also known as intermittent flow). Conservation equations are derived based on the assumptions of the unit cell model. The main results concerning the motion of long bubbles and liquid slugs are reviewed.
