Numerical Simulation on Sand Production Based on Laboratory Gas Hydrate Production Experiment

Journal of Marine Science and Engineering, 2023
Gas from natural gas hydrate (NGH) is priced competitively with gas prices. Most marine NGH is stored in low cementing strata, which easily cause sand production problems, restricting the commercial production and environmental safety of NGH’s ...

Optimizing of metal foam design for the use as a heat exchanger [PDF]

, 2018
The work deals with possibilities of using this specific material. It is focused on cast metal foams with a regular arrangement of internal cells and it refers to already used casting technologies - the production of metal foamswith the aid of sand cores.

Thermal imaging on simulated faults during frictional sliding [PDF]

, 2006
Heating during frictional sliding is a major component of the energy budget of earthquakes and represents a potential weakening mechanism. It is therefore important to investigate how heat dissipates during sliding on simulated faults. We present results

The sustainable global energy economy: Hydrogen or silicon? [PDF]

, 2008
A sustainable global silicon energy economy is proposed as a potential alternative to the hydrogen economy. This first visualisation of a silicon energy economy is based on largescale and carbon-neutral metallic silicon production from major smelters ...

Experimental Study of Sand Production during Depressurization Exploitation in Hydrate Silty-Clay Sediments

Energies, 2019
Silty-clay reservoirs are a weak point in sand production and sand control studies due to their low economy. However, China’s marine natural gas hydrates (NGH) mostly exist in silty-clay sediments, which restrict the sustainable and efficient ...

Influence green sand system by core sand additions [PDF]

, 2012
Today, about two thirds of iron alloys casting (especially for graphitizing alloys of iron) are produced into green sand systems with usually organically bonded cores. Separation of core sands from the green sand mixture is very difficult, after pouring.

Fine Particle Migration in a Gas Hydrate Sand: Single- and Two-Phase Fluid Using a Device for Observation at the Pore Scale

Journal of Marine Science and Engineering
The production of natural gas hydrates will change the cementation strength, porosity, and effective stress in the stratum, which may lead to engineering and geological disasters.
