| Transport behaviors with the surface charge ranging from 0 e to −12 e. (a) Axial velocity profiles with different surface charge numbers. (b) Slip length as a function of the surface charge number. Slip length decreases with increasing surface charge number. (c) Corresponding Coulomb potential profiles with different surface charge numbers. A higher surface charge number generates a higher potential barrier that is more difficult for water molecules and ions to get through. |
