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.

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

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 ...

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 ...

TRANSITION IN THE FRETTING PHENOMENON [PDF]

open access: yesFiabilitate şi Durabilitate, 2022
Fretting regimes were first mapped by Vingsbo. In a similar way, three fretting regimes will be considered: stick regime,slip regime and mixed regime.
