Evaluation analysis of correlations for predicting the void fraction and slug velocity of slug flow in an inclined narrow rectangular duct

Nuclear Engineering and Design, 2014
Abstract A visualized investigation was conducted on inclined upward air–water slug flow in a narrow rectangular duct with the cross section of 43 mm × 3.25 mm. The slug velocity and void fraction were obtained through image processing. 46 correlations for predicting void fraction, covering the types of slip ratio, Kβ, Lockhart and Martinelli, drift ...

Analysis of Gas-Solids Feeding and Slug Formation in Low-Velocity Pneumatic Conveying

Particulate Science and Technology, 2003
Gas and solids feeding is a key operation in pneumatic conveying of particulate materials. This article presents an analysis of the interfacing effects between a nozzle gas supplier, a rotary valve solids feeder with dropout box, and the pipeline of a pneumatic conveying test rig for low-velocity dense-phase flow.

Scale-up technology in low-velocity slug-flow pneumatic conveying

Powder Technology, 2002
Abstract To design a low-velocity slug-flow pneumatic conveying system, not only should we predict total pipeline pressure drop, but also locate upper and lower dense-phase boundaries [R. Pan, P.W. Wypych, and J. Yi, Design of Low Velocity Slug-Flow Pneumatic Conveying Systems, 6th International Conference on Bulk Materials Storage, Handling and ...

Propagation Velocity of Turbulent Slugs and Streaks in Transition Pipe Flow

The Physics of Fluids, 1969
Taking account of experimental observations on the transition process, an elementary theory is developed for estimation of propagation velocity of the rear end of turbulent slugs and streaks which constitute a major feature of the transition process in pipe flow.

The bubbly-slug transition in a high velocity two phase flow

1964
A possible mechanism for the transition between bubbly and slug flow is proposed and tested in a simulated slug flow system. No sudden collapse of slug flow with increasing velocity is found and it is concluded that: a. Slug flow is generally stable at voids greater than 35%. b.
