Abstract
The viscosity of the gases are calculated for different fugacities and Knudsen numbers based on self-diffusivity coefficients for two capillary sizes of 2 and 4 nm. The computed viscosities of all gases decrease as pressure increases. For all gases, the viscosity under confinement are lower than their nominal values. Viscosity values for argon and methane increase approximately linearly with fugacity for both capillaries. The viscosity values of neon for the capillaries are almost the same for fugacities less than 90 atm. It is also shown that the viscosity models for gases under confinement are not good candidates to be used in organic nanopores due to adsorption of gases to pore surface.
