Sentence examples for dual bubble from inspiring English sources
Variations in the drag force with the solid Taylor bubble's lateral displacement from the tube axis were determined in single and dual bubble systems.
In this comparative study, we have examined various approaches (i.e. constant and variable single bubble size models, dual bubble size models, and both homogeneous and inhomogeneous MUSIG models).
In the dual bubble system, the drag force measured on a trailing bubble at the center of the pipe increased gradually with the increasing separation distance up to about two pipe diameters, while beyond this region the drag force remained essentially constant.
We establish the dual-bubble-size model, an extended EMMS approach for gas liquid systems.
A dual-bubble-size (DBS) model is proposed to approximate the heterogeneous structure of gas liquid systems based on a single-bubble-size (SBS) model previously established.
In this study, a novel model is proposed to calculate the ratio on the basis of the Dual-Bubble-Size (DBS) model.
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 (SCMF-A) integrating the DBS model into CFD simulation.
Then a new reactor model is developed to replace the empirical correlations for gas holdup with the dual-bubble-size (DBS) model, and the empirical contraction factor is eliminated by introducing the gas state equation and overall mass balance.
Using propane, butane and air as the dispersed phases and different SDS PEG solutions as the continuous phases, two kinds of bubble generating phenomena, named "single-bubble generation" flow and "dual-bubble generation" flow, were observed in experiment and uniform bubbles with average diameters ranging from 391 μm to 713 μm and polydispersity less than 2.9% were successfully prepared.
This transition is understood to be the result of transition in vortex breakdown modes of the swirling flow field from dual-ring VB bubble to central toroidal recirculation zone (CTRZ).
The streamline patterns show two characteristic flow modes, single bubble and dual rings, in the bluff-body effective regime.
