Pressure drop and slug velocity in low-velocity pneumatic conveying of bulk solids

Powder Technology, 1997
Low-velocity slug flow pneumatic conveying is being applied increasingly in industry and to a wide range of bulk solid materials. However, to date, most investigations have focused on bulk solid materials with regular shape (e.g. plastic pellets, wheat) and very little work has been undertaken with irregular-shaped materials (e.g.

Analysis of horizontal slug translational velocity based on the image processing technique

2019 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2019
Slug flow is a common flow regime that occurs in chemical industries, petroleum and power generation. The aim of this paper is to investigate the correlation between the slug bubble translational velocity and the air-liquid superficial velocity based on the development of a new image processing procedure.

Rise velocities of slugs and voids in slugging and turbulent fluidized beds

Korean Journal of Chemical Engineering, 1989
Using the cross-correlation function of two pressure fluctuation signals, the rise velocities of slugs and voids and the slug frequency in the slugging and turbulent fluidized beds of glass beads(dp= 0.362 mm) have been determined in a 0.1 m-lD x 3.0 m high Plexiglas ...

Velocity distribution in horizontal slug flow

International Journal of Multiphase Flow, 1984
An experimental device for measurement of the velocity distribution in a two-phase slug is developed. Velocity profiles both in the film and the liquid slug besides velocity variation along the pipe bottom (at a distance of 1 mm) through the slug front are presented.

ON THE RISE VELOCITY OF SLUGS IN FLUIDIZED BEDS

Chemical Engineering Communications, 1983
Abstract A quantitative description of non-uniform, dilute-phase, volume fraction and superficial velocity in two-phase, bubble-slug-flow, fluidized beds is presented. The appropriate expression for absolute slug velocity is where the distribution coefficient, Co takes on a value of 1.20, and ūs is a weighted-mean value over the bed cross-section. Only

New method for bubble/slug velocity measurement in small channels

Review of Scientific Instruments, 2020
Based on the C4D technique and cross correlation velocity measurement technique, a new method for bubble/slug velocity measurement of the gas–liquid two-phase flow in small channels is proposed. A new C4D sensor, which is suitable for the parameter measurement of the gas–liquid two-phase flow in small channels, is developed by introducing the principle

Liquid velocity distribution in slug flow in a microchannel

Microfluidics and Nanofluidics, 2011
The liquid velocity distributions in two-phase slug flows in a nearly rectangular microchannel etched on a microfluidic chip were investigated using a three-dimensional tracking method for submicron fluorescent particles seeded in the working liquid (water).

The pipeline flow of paste slugs: Part II. Pressure gradients and velocities of trains of slugs

The Canadian Journal of Chemical Engineering, 1968
AbstractPrevious studies of the pipeline movement of single paste slugs of coal have been extended to determine the velocities of, and the pressure gradients along, trains of slugs. The measurements were taken in a 70‐foot long, closed‐loop line made from 0.95‐inch bore, rigid plastic tubing.
