Composite thermal conductivity in a large heterogeneous porous methane hydrate sample

Article Abstract:

Inverse modeling is used to analyze the laboratory data and also determine the composite thermal conductivity of the porous methane hydrate sample as a function of density. The analysis has shown that the sample heterogeneity should be considered in thermal conductivity measurements of hydrate systems.

Modeling heating curve for gas hydrate dissociation in porous media

Article Abstract:

A method for modeling the heating curve for gas hydrate dissociation in porous media at isochoric conditions (constant cell volume) was presented. The shape factor (F) of hydrate-water interface was found equal to 1, supporting a cylindrical shape for the hydrate particles during hydrate dissociation.
