Stability-constrained multi-fluid CFD models for gas-liquid flow in bubble columns
, 2013 We have proposed a Dual-Bubble-Size (DBS) model featuring a stability condition describing the compromise of two dominant mechanisms, and then a stability-constrained multi-fluid model (SCMFA) integrating the DBS model into CFD simulation.

Hydrodynamics of three-phase fluidized beds
, 1978 The hydrodynamics of three-phase (gas-liquid-solid) fluidized beds has been studied in two columns with inside diameters of 7.62 and 15.2 cm respectively. The minimum gas and liquid velocities necessary to fluidize various types of solids were determined

Pressure Drop Models for Gas/NonNewtonian Power-Law Fluids Flow in Horizontal Pipes
, 2014 Models commonly used in literature are evaluated versus 696 data points to predict the pressure drop of gas/non-Newtonian power-law fluids flow in horizontal pipes. Suitable models are recommended.

CONTINUOUS CONTACT OF A GAS WITH LIQUID-SOLID SLURRIES.
, 1987 A multistage agitated column was investigated for use as a countercurrent gas-slurry contractor. Experimental results show that at high gas rates and low impeller speeds the impellers became flooded with air and the rising gas approached slug flow as in ...

Multiphase flow measurement in the slug regime using ultrasonic measurement techniques and slug closure model [PDF]
, 2006 Multiphase flow in the oil and gas industry covers a wide range of flows. Thus, over the last decade, the investigation, development and use of multiphase flow metering system have been a major focus for the industry worldwide. However, these meters do

Exploring the effects of salts on gas dispersion and froth properties in flotation systems
, 2006 Several mineral flotation plants utilize process water with high soluble salt content. The processing of soluble minerals, the use of recycle streams, sea or well water give rise to this situation.
