Rock salt in China is primarily bedded salt, usually composed of many thin salt layers and interlayers (e.g. anhydrite, mudstone, and glauberite). Thus, the feasibility analysis of abandoned salt caverns located in salt beds to be used as Underground Gas Storage (UGS) facilities is full of...

Three-dimensional numerical simulations are performed to investigate the effects of nitrogen (N2) and sulfur dioxide (SO2) impurities on the solubility trapping mechanism of carbon dioxide (CO2) geological storage. Dissolved CO2 has been suggested to increase the density of the aqueous phase....

Numerical analyses are performed to study the fluid dynamic behaviours of the solubility trapping in the context of CO2 storage in deep geological formations. Dissolution of CO2 into the underlying brine increases the density of brine, leading to a gravitational instability. This instability...

We present simulation results on a novel dew-point evaporative air conditioner which was designed based on a counter-flow closed-loop configuration consisting of separated working channels and product channels. The novel evaporative air conditioner is able to cool air to temperature below...

The supersonic separation is a novel technology in the natural gas dehydration for its compact design and fewer emissions. The other fascinating advantage is that the diffuser can convert kinetic energy into pressure energy to improve the energy efficiency. The mechanism of the pressure recovery...

In order to research the failure mechanism of Solid Oxide Fuel Cell (SOFC), an unsteady state two-dimensional model that considers the carbon deposition is presented. Navier–Stokes (N–S) equations, heat transfer equation, mass transfer equation, electron and ion transport equation are solved...

Parabolic-trough collectors (PTC) solar systems are one of the most promising of a wide range of the available solar technologies. Continuous breakthroughs are being achieved. Mainly due to the considerable amount of solar PTC plants that are being under operation in different countries. Within...

In this work a flat plate collector (FPC) with plastic transparent insulation materials (TIM) and a low-cost overheating protection system destined for heat supply from 80 to 120°C is presented. A ventilation channel with a thermally actuated door is inserted below the absorber allowing to...

The kinetic behaviors of methane hydrate dissociation under depressurization in porous media are investigated through experimental and numerical simulations. Hydrate samples with low gas saturations (SG⩽0.10) are synthesized in the pilot-scale hydrate simulator (PHS), a novel three-dimensional...

Gasification of torrefied biomass is a promising technique for producing synthesis gas (syngas) of higher quality than has previously been available. In this study, in order to evaluate the potential of the technique, gasification processes for three different materials, which include raw...
