Natural gas thermal conductivity

WebThe gas state thermal conductivity is linked to the collision of the molecules which transfer the energy from one to the other. A way to reduce the gas state thermal conductivity is to reduce the pore size of the material below certain dimension to lead to the so-called Knudsen effect. Web24 de jul. de 2015 · 1 Introduction. The thermal properties of hydrate-bearing sediments play an essential role in understanding the hydrate formation processes (e.g., heat flux, geothermal gradient, and hydrate stability zone), evaluating the potentials of gas production from natural accumulations, and hydrate dissociation triggered seafloor instability.
