Dripping, Jetting and Regime Transition of Droplet Formation in a Buoyancy-Assisted Microfluidic Device [PDF]

open access: yesMicromachines, 2020
Buoyancy-assisted droplet formation in a quiescent continuous phase is an effective technique to produce highly monodispersed droplets, especially millimetric droplets. A comprehensive study combining visualization experiment and numerical simulation was

Examining the Effect of Flow Rate Ratio on Droplet Generation and Regime Transition in a Microfluidic T-Junction at Constant Capillary Numbers

open access: yesInventions, 2018
The focus of this work is to examine the effect of flow rate ratio (quotient of the dispersed phase flow rate over the continuous phase flow rate) on a regime transition from squeezing to dripping at constant capillary numbers.

Defining features of diverse and productive agricultural systems: An archetype analysis of U.S. agricultural counties

open access: yesFrontiers in Sustainable Food Systems, 2023
Prior research suggests that greater spatial diversity in crops and land use is associated with higher crop yields and improved ecosystem function. However, what leads to the emergence of agricultural systems that meet both productivity and ecological ...

Trickle/pulse flow regime transition in downflow packed tower involving foaming liquids [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2012
The most of past studies in foaming trickle bed reactors aimed at the improvement of efficiency and operational parameters leads to high economic advantages. Conventionally most of the industries rely on frequently used gas continuous flow (GCF) where

Tunisian Military and Regime Change

open access: yesPoliteja, 2021
This paper has several research objectives. They are related to the description of the position of the military in the non-democratic regime in Tunisia, as well as to the clarification of its role in the overthrow of the regime, that is, to the ...

THRESHOLDS OF UPPER-STAGE PLANE BED REGIME FOR INTENSE BED LOAD IN OPEN CHANNEL [PDF]

open access: yesCivil Engineering Journal, 2016
Results are discussed of laboratory experiments on criteria determining the transition between the regime of dunes and the upper stage plane bed (UPB) regime and the transition between the UPB regime and the regime of wavy flow.

A Roadmap to a Successful Exchange Rate Regime Transition: Takeaways from 6 African Transitions

open access: yesOrganizations and Markets in Emerging Economies, 2023
This article investigates the role of monetary policies in the success of exchange rate regime transition and the mitigation of related risks. We adopted a comparative methodology for three types of regime switches using 3 GARCH family models and data ...

Bubble Column Reactors: the Variables Influencing the Mono-dispersed Homogeneous Flow Regime

open access: yesChemical Engineering Transactions, 2023
The fluid dynamics of large-diameter bubble columns explicates in six flow regimes emergin upon an increase in the gas flow rate and can be described and predicted via correct modelling of the flow regime transition coordinates. This study focuses on the

Adiabatically changing the phase-space density of a trapped Bose gas [PDF]

open access: yes, 1996
We show that the degeneracy parameter of a trapped Bose gas can be changed adiabatically in a reversible way, both in the Boltzmann regime and in the degenerate Bose regime.
