Abstract:
Wet compression is widely used to reduce compression work and improve efficiency in gas turbines. However, wet compression has not been industrially applied in the compressed air energy storage system (only few studies on isothermal compressed air energy storage system exist), which has an urgent demand to reduce the compression work. The high-pressure section of the compressed air energy storage system usually contains supercritical air, and the influence of supercritical wet compression is not yet clear. Thus, in this study, supercritical wet compression was numerically investigated in a cen

This paper presents a novel swing compressor with no valves employed in air compression. The design and work principle of this swing compressor are introduced. And the effects of discharge port, exhaust cavity, and crank speed on the performances of this compressor are analyzed. Under the same operating conditions and dimensions, the size of exhaust cavity mainly depends on the discharge port width. Additionally, the exhaust cavity angle has a direct impact on the compression process, whether it is over-compression or under-compression. And the over-compression loss can be designed below 2%. O

Abstract:
Air is usually compressed adiabatically in the compressor. As the operating speed of compressors can be several thousand rpm, heat generated during compression cannot be sufficiently transmitted to the environment in such a short time. It is for this reason that compressor efficiency is limited. Isothermal compression could be an alternative choice applied on industrial compressor and compressed air energy storage (CAES). This paper proposed a new kind of piston to perform isothermal compression. Surface area of such isothermal piston structure is larger. A certain amount of fluid at the chamb

The combination of a liquid piston gas compressor and a solid metal insert can achieve a near-isothermal compression process, which can greatly contribute to improving the system efficiency of a compressed-air energy storage system. To examine the effectiveness of the insert at various pressure levels, compressions were performed in a liquid piston compressor with and without copper wire mesh inserts at three different pressures of 1, 2, and 3 bars. The use of inserts increased isothermal compression efficiencies by 8–10% from the baseline isothermal efficiencies about 83–87%, while the compro

The heat pump is controlled through the circuit containing the refrigerant and it is therefore crucial that this circuit is functional.

Abstract:
When a large area of open gob collapses suddenly, a windblast is produced that can cause considerable damage throughout the infrastructure of a mine. In a few cases, the windblast has been accompanied by ignitions of methane and/or coal dust. Analytical and numerical analyses investigated the transient behavior of the air through the small time period during which the roof is falling. This is sufficiently short to allow adiabatic compression of the air, i.e. negligible heat transfer to rock surfaces. Controlled escape of the air via interconnecting entries limits the build-up of air pressure.

Water infiltration into the unsaturated zone especially in a shallow water table environment is affected by air compression ahead of the wetting front and air counterflow. Neglecting air compression in infiltration modeling can overestimate infiltration and infiltration rates, whereas not accounting for air counterflow can underestimate infiltration and infiltration rates due to unrealistic buildup of air pressure resistance ahead of the wetting front. A method, derived on the basis of the Green and Ampt (1911) infiltration model, is introduced to simulate air compression and air counterflow d

AbstractAll engines involve the raising of pressure in the engine’s medium, be it liquid compression of water, piston-cylinder compression of air or compression by aerodynamic forces. The last is the hardest because it is required to be efficient and stable. An aerodynamic air compressor works by slowing velocities to raise pressure. The airfoil has a difficult time doing this reliably and well and so does the compressor. When it does, it allows for amazing performance of the engine in terms of power and efficiency.

In an isothermal compressed air energy storage (CAES) system, it is critical that the high pressure air compressor/expander is both efficient and power dense.

In our previous works, optimization of the compression/expansion trajectory has been proposed as a means to mitigate this trade-off.

Abstract:
In recent years, several papers have been written regarding the use of centrifugal compression technology to handle applications in which the process gas entering the equipment contains a significant amount of liquids, and can therefore be considered a wet gas. One such application that is currently being considered by many oil and gas operators is the installation of processing and compression equipment on the sea bed, to directly handle the process gas stream in close proximity to the wellhead. Other applications also exist topside, in which the operator would benefit from the installation o

Abstract:
La fermeture des centrales nucléaires et le développement de l’énergie solaire et éolienne rendent la production d’électricité plus volatile. De nouveaux systèmes de stockage sont nécessaires pour s’assurer que l’électricité est disponible au moment où elle est nécessaire. Le stockage adiabatique d’air comprimé représente une technologie prometteuse. Il utilise l’excédent de production des installations solaires et éoliennes pour comprimer l’air ambiant et le stocker dans une cavité souterraine. Au besoin, l’air comprimé est à nouveau détendu et entraîne alors une turbine qui produit de l’élec

Abstract:
A semi-empirical elasto-plastic constitutive model with a hyperbolic stress-strain curve was developed with the goal of predicting the seismic compression of unsaturated sands in the funicular regime of the soil-water retention curve (SWRC) during undrained cyclic shearing. Using a flow rule derived from energy considerations, the evolution in plastic volumetric strain (seismic compression) was predicted from the plastic shear strains of the hysteretic hyperbolic stress-strain curve. The plastic volumetric strains are used to predict the changes in degree of saturation from phase relationships

Abstract:
Develop an active air control system that, when installed on a turbocharged-engine system, will reduce NOX emissions below the levels of the system alone. While the turbocharged-engine system allows the natural gas compression industry to decrease pollutant emissions via increased air flow, the physics of the system and the environments in which these systems operate restrict further advancements. A new model, the Charge Air Integrated Manifold Engine Numerical Simulation (CAIMENS). The CAIMENS model was used to: Quantify the effects of charge air imbalance between cylinders in terms of NOX pr

Abstract:
There are over 7000 of large bore integral compressor engines distributed along the interstate and intrastate natural gas pipelines in the United States for gas compression. Methane emissions from large bore engines stem primarily from poor combustion efficiency. This study aims to improve the combustion efficiency of these engines, by reducing the amount of unburned methane that can escape through the crankcase vent and the exhaust gas emissions. Two broad approaches are taken to achieve this objective using experimental testing and computational studies: hydrogen blending and late cycle high

Abstract:
Large-bore, natural gas-fueled engines are used for gas compression at over 1700 compression stations across the US, and methane emissions have presented a challenge to their optimization over the years. A significant root of this problem has been linked to the level of air-fuel mixing in the main combustion chamber of these engines as poor mixing results in low combustion efficiency. High-pressure fuel injection is believed to be a significant way to improve air-fuel mixing in natural gas engine combustion chambers. The purpose of this present study is to determine the sensitivity of in-cylin

Abstract:
Heat pumps are an excellent solution to supply heating and cooling for indoor space conditioning and domestic hot water production. Conventional heat pumps are typically electrically driven and operate with a vapour-compression thermodynamic cycle of refrigerant fluid to transfer heat from a cold source to a warmer sink. This mature technology is cost-effective and achieves appreciable coefficients of performance (COP). The heat pump market demand is driven up by the urge to improve the energy efficiency of building heating systems coupled with the increase of global cooling needs for air-cond
