Gas cushion model and hydrodynamic boundary conditions for superhydrophobic textures [PDF]

open access: yesPhysical Review E, 2014
Superhydrophobic Cassie textures with trapped gas bubbles reduce drag, by generating large effective slip, which is important for a variety of applications that involve a manipulation of liquids at the small scale. Here we discuss how the dissipation in the gas phase of textures modifies their friction properties.

The impact of reservoir properties on mixing of inert cushion and natural gas in storage reservoirs [PDF]

open access: yes, 2006
Underground natural gas storage is a process which effectively balances a variable demand market with a nearly constant supply of energy provided by the pipeline system.

A seakeeping analysis method for an air-lifted vessel [PDF]

open access: yes, 2008
A seakeeping analysis in the frequency domain is presented to predict the motion response of an airlifted vessel (ALV) in waves. The ALV is supported by pressurised air in two separate cushion chambers; the pressure variation in the cushions has a ...

DEM analysis of micromechanics and buffering capacity of superquadric mixture granular materials under impact load

open access: yesFrontiers in Earth Science, 2022
As one of the most common geological disasters, rockfalls seriously threaten the safety of linear projects such as roads, railways, and oil and natural gas pipelines. The rigid protective structures that are used for disaster reduction are easily damaged

A new anti-leakage method used in air cushion surge chamber

open access: yesShuili Shuiyun Gongcheng Xuebao, 2017
The air cushion surge chamber has a good function for reflecting water-hammer waves. That is why it can effectively reduce water hammer pressure in the pressure pipeline when the load of hydroelectric power station change dramatically.

Numerical simulation research on coupling of gas generator with large aspect ratio and multi-vent

open access: yesAIP Advances, 2021
The pressure distribution of the combustion system with a large aspect ratio is uneven, and the process of gas flowing out through the vent holes arranged along the axial direction is inconsistent.

Comprehensive Research on Construction and Stability of Horizontal-Well Cavity Natural Gas Storage in Thinly Bedded Salt Rocks in China

open access: yesEnergies, 2023
This study aimed to overcome the difficulty of conducting the horizontal-well cavity leaching test in the field and to investigate the long-term stability of the horizontal-well salt-cavity natural gas storage. The simulation test design is combined with

An Analysis of Relationship between Cushion Gas and Gas Withdrawal in Depleted Gas Reservoir as a Gas Storage

open access: yesJournal of the Korean Institute of Gas, 2013
Abstract - Depleted gas reservoir has been already explored and its geologic data, along with its reservoir properties, are already known through seismic exploration and drilling. Therefore it would be less difficult to develope a gas storage from depleted gas reservoir. Cushion gas which remains in the reservoir to maintain pressure affects withdrawal

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

-Based Cushion Gas

open access: yes, 2019
Power-to-gas (PtG) stores chemical energy by converting excess electrical energy from renewable sources into an energy-dense gas. Due to its higher available capacity compared to surface-based storage technologies, subsurface storage in geological ...
