FIG. 1.

(a) Counter-ion concentration profiles across the channel (channel width is in the direction) for case 1 and case 2; corresponds to the innermost layer of the lower channel wall; (b) comparison of the water velocity profile for case 1 and case 2, as obtained from the continuum theory and the MD simulations. In the continuum simulation, a no-slip boundary condition is applied at a position of from the surface—this is consistent with the MD observation. A constant viscosity of is used, which gave the best match of the velocity profile curvature in the central portion of the channel with the MD results.

FIG. 2.

Effective viscosity of water across the channel in the positively charged channel (a) and negatively charged channel (b). The effective viscosity is scaled by the viscosity of water in the central portion of the channel .

Diffusion coefficient of water in the direction parallels to the channel surface in the positively charged channel (a) and negatively charged channel (b).
