摘要: How hydrodynamic dispersion is affected by wall slip remains to be fully understood. An attempt made in this article looking into issue for some elementary pressure-driven flows. Both the long-time Taylor–Aris and early-phase convection-dominated are investigated, analytically numerically, respectively. The mean variance of residence time distribution also examined. In basic case where walls a parallel-plate channel have equal lengths, general reduce spread solute cloud finite either increasing convection speed or decreasing dispersivity. However, effect on can diminished even reversed unequal lengths and/or phase exchange with wall. regime following recently proposed transport-based method, determine how elution profiles may change axial positions depending slip.
