4 We theoretically study how the electroosmotic fluid velocity in a charged cylindrical nanopore in a thin solid state membrane depends on the pore's geometry, membrane charge, and electrolyte concentration. We find that when the pore's length is comparable to its diameter, the velocity profile develops a concave shape with a minimum along the pore axis unlike the situation in very long nanopores with a maximum velocity along the central pore axis. This effect is attributed to the induceddoi:10.1103/physreve.95.063105 pmid:28709345 fatcat:romhy42uong7jmejgaptdisqaq
