Abstract The use of liquid–liquid slug flow in the capillary microreactor is a promising technique for intensifying heat and mass transfer in liquid–liquid reactions. Although the concept has so far been exploited without much reference to the detailed hydrodynamics involved, these are nevertheless inherently crucial to its potential for providing ...

A model for slug length distribution in gas-liquid slug flow
International Journal of Multiphase Flow, 1993Summary: Intermittent, or slug flow, is a very common occurrence in gas-liquid two-phase pipe flow. Usually slug flow is an undesirable flow pattern since the existence of long lumps of liquid slugs that move at high speed is unfavorable to gas-liquid transportation.

Void distribution in slug flow
International Journal of Multiphase Flow, 1993Abstract Air-water slug flow at atmospheric conditions in horizontal pipes of 31 and 53 mm i.d. has been characterized experimentally with local (optical) and cross-sectional (conductance) probes. The objective of the work is to improve the description of slug flow and the closure relations required in mean kinematic slug flow models.

Sensitivity of Slug Flow Mechanistic Models on Slug Length
Volume 7: Offshore Geotechnics; Petroleum Technology, 2009Slug flow is one of the common flow patterns in gas and oil production and transportation. One of the closure relationships required by the multiphase flow mechanistic models is slug length correlation. There are several closure relationships proposed in the literature as function of pipe geometry, pipe diameter and inclination angle, and to a lesser ...

Entrance effects can persist for great lengths, L/D = 300, and long times, in developing two phase flows. Wall shear stresses at moderate and low velocities contribute only slightiy to the pressure drop in slug flows. Bubblerise velocities in slug flow are quite sensitive to the velocity profile in the water ahead of the bubbles.

The paper begins by summarising theory and experimental data concerning the rate of rise of a large gas bubble or slug through an inviscid liquid in a vertical tube, or between two flat plates. Experimental data show that the theory can be used to predict the rise of slugs in fluidised beds.

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 ...

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 ...

Pipes Conveying Horizontal Slug Flow
2020Pipe–soil interaction has been intensively investigated both theoretically and experimentally due to its importance in the design of seabed pipelines. In recent years, the effects of single phase, steady internal flow on the dynamic response of seabed pipelines have received increasing attention.
