Low liquid loading flow occurs very commonly in the transport of any kind of wet gas, such as in the oil and gas, the food, and the pharmaceutical industri... MA Ballesteros,N Ratkovich,E Pereyra - Journal of Energy Resources Technology-transactions of The Asme 被引量: 0发表: 2020年 Pre...
Gas-liquid Two-phase Bubbly FlowGas HoldupUltrasonic Measurement MethodHigh-speed CameraSound Field SimulationBased on ultrasonic sound pressure attenuation, the ultrasonic pulse transmission method is proposed for measuring gas holdup in gas-liquid two-phase bubbly flows. Two ultrasonic transducers are ...
An experimental investigation was carried out to determine the effects of gas and liquid flow rates and packing size on the liquid phase axial dispersion coefficient and the liquid holdup in a gas-liquid, cocurrent, upflow packed column... GJ Stiegel,YT Shah - 《Industrial & Engineering Chemis...
Flow patterns, pressure loss and liquid holdup for gas-liquid co-current downflow have been studied in glass beds and in cylindrical and spherical downflow have been studied in glass beds and in cylindrical and spherical Co/Mo/AlOcatalyst packing with foaming and nonfoaming liquids. The different...
The liquid velocities and gas holdups in the riser and downcomer of three-phase internal-loop airlift reactors with Newtonian and non-Newtonian fluids were studied. The reactor was constructed of 19 cm ID Plexiglas column and 250 cm in height. The inside diameters of the draft tube were 9,...
Results indicate that only in the bed packed with glass spheres of 10 mm diameter may two-phase flow in the interparticle voids occur. For smaller particles flow maldistributions are found and pure gas flow in part of the voids is anticipated, simultaneous to regular gasliquid flow in the ...
Particle mass transfer and liquid hold-up in packed beds with upward concurrent gas-liquid flowThe knowledge of the flow patterns of each phase of bubble column reactors is of considerable importance for the rational design and scale-up. The hydrodynamic models for the liquid phase have been ...
Hydrodynamics in an up flow jet-loop reactor (JLR) is experimentally investigated. The overall gas holdup, radial and axial distributions of local gas holdup and liquid velocity are presented. A modified drift-flux model was developed for correlating the "S-shape" relationship of overall gas hol...
2.In this paper,the prediction of void fraction and pressure drop for upward gas-liquid annular flow in a vertical annulus is studied.对垂直同心环形管内上升气液环状流的截面含气率及压降预测进行了研究 。 3.A sensor with semi-circle capacitor is adopted to on-line automatically and averagely me...
