Interaction potential between water-like particles.
Schematic depiction of the simulation box with the nanotube, reservoirs, and fluctuating walls. The cylindrical channel in the center has a radius a and length L c . The reservoirs have height L.
Axial mean square displacement versus time for channel radius a * = 1.25, 1.5, 2.0, 5.0, and 10.0.
Diffusion coefficient inside nanotube, D x, NT, in units of non-confined diffusion, D x, bulk, for different nanotube radius. The error bars are smaller than the data point. The dotted line is a guide to the eye.
Radial density profile for different values of radius: (a) a * = 1.25, (b) a * = 1.5 (c) a * = 2.0, (d) a * = 4.0, (e) a * = 7.0, and (f) a * = 10.0.
Snapshots of the system for (a) a * = 2.0 and (b) a * = 1.5.
Total density inside the nanotube as function of the tube radius for T * = 0.25 and p * = 0.7. The error bars are smaller than the data point. The line is a guide to the eye.
Axial density profile for a nanotube with radius (a) a * = 1.5, (b) a * = 2.0, and (c) a * = 7.0.
