Effects of the consistency variation on the peristaltic transport of a non-Newtonian power-law fluid through a tube have been investigated by taking into account the existence of a peripheral layer. It is shown that the flow rate flux, for zero pressure drop, increases as the amplitude of the peristaltic wave increases but it decreases due to the pseudoplastic nature of the fluid. It is also noted that, for zero pressure drop, the flux does not depend on the consistency of peripheral layer while the friction decreases as this consistency decreases. However, for nonzero pressure drop, the flux increases and the friction force decreases as the consistency of peripheral layer fluid decreases.
通过考虑外围层的存在，研究了稠度变化对非牛顿幂律流体在管道中蠕动传输的影响。结果表明，在零压降情况下，流量通量随着蠕动波振幅的增加而增加，但由于流体的假塑性性质而减小。还注意到，在零压降时，通量不依赖于外围层的稠度，而摩擦力随着稠度的降低而减小。然而，在非零压降情况下，随着外围层流体稠度的降低，通量增加而摩擦力减小。
