Molecular Dynamics of Gas Hydrates, Aqueous Solutions, and Absorption Refrigeration
This community applies molecular dynamics simulations and thermodynamic modeling to understand the formation, structure, and phase behavior of gas hydrates and aqueous electrolyte solutions, primarily for natural gas processing and absorption refrigeration systems.
The work focuses on simulating the interaction of water molecules with guest gases like methane and carbon dioxide to predict hydrate formation conditions and stability. Recurring themes include the effect of salts such as sodium chloride and lithium bromide on phase equilibria, the role of ionic liquids in modifying hydrate properties, and the thermodynamic modeling of solid-liquid and liquid-liquid phase separation. The research also addresses the specific challenges of CO2 hydrate formation and the use of molecular dynamics to analyze the structural changes in aqueous solutions at different temperatures and pressures.
The largest share of the community's output is found in bromine research, accounting for 1.8% of all bromine research, followed by chlorine at 1.2% and sodium at 0.8%. Hydrogen research contributes the highest number of papers within this group, with 3,972 entries.
The community comprises 22,393 papers, published most frequently in the Journal of Chemical & Engineering Data, The Journal of Chemical Physics, and The Journal of Physical Chemistry B.
Recent work includes molecular dynamics simulations of water-soluble polymers inhibiting methane hydrate formation, studies on the seepage-path-dependent storage capacity of CO2 hydrates in reservoirs, and investigations into the stabilization of protein and colloidal dispersions by amino acids.
