Experimental and CFD Investigation into Using Inverted U-Tube for Gas Entrainment

open access: yesApplied Sciences, 2020
An experimental and numerical study is presented in the current work for gas entrainment using an inverted vertical U-tube. Water flows vertically up in an inverted U-tube which creates a low-pressure region in the tube upper portion.

Root and microbial contributions to anoxic microsite formation in the rhizosphere: a microfluidic approach. [PDF]

open access: yesNew Phytol
Summary Plant root‐associated anoxic microsites may influence the fate of nutrients and contaminants in the rhizosphere, but their dynamics remain relatively unknown. To examine the formation of root‐induced anoxic microsites over space and time, we use microfluidic devices integrated with transparent, planar oxygen sensors in a wheat (Triticum ...

Study on the Hydraulic Characteristics in the Forebay of Inverted Siphon

open access: yes, 2023
The inverted siphon is a common hydraulic structure used in large-scale, long-distance water conveyance projects. Due to the limitations of terrain, landform and geological factors, the dimensions of the forebay of the inverted siphon are often limited.

Hydrophilic polymeric coatings for enhanced, serial-siphon based flow control on centrifugal lab-on-disc platforms [PDF]

open access: yes, 2012
In this paper, we implement rotational flow control on a polymeric microfluidic “lab-on-a-disc” device by combining serial siphoning and capillary valving for sequential release of on-board stored liquid reagents.

On the Head-loss of Inverted Siphon [PDF]

open access: yes, 1955
I surveied the actual head-loss of inverted siphon, computed it by formula, or studied its samples. So I got next results, (I) head-loss of Fukazawa inverted siphon-it has passed 14years after it was made-by computation is same to it by survey. (2) ideal

The Secret Siphon [PDF]

open access: yes, 2011
Although the siphon has been in use since ancient times, the exact mechanism of operation is still under discussion. For example, most dictionaries assert that atmospheric pressure is essential to the operation of a siphon rather than gravity.

Driving factors of China’s city-level carbon emissions from the perspective of spatial spillover effect

open access: yesCarbon Management, 2019
We use the 2004–2016 China prefecture-level city data to construct a STIRPAT-based spatial econometric model as an empirical test for the driving factors of city carbon emissions.

Finite Element Analysis of Shaba Inverted Siphon Structure [PDF]

open access: yesAdvances in Engineering Research, 2014
Abstract—The numerical simulation study for water conveyance of inverted siphon on water security is of great significance. The inverted siphon is thin-walled concrete structure, and cracks will appear according to temperature loads. Generally speaking, the temperature difference between the internal and external and the basic difference of temperature
