What does this research mean for the field?

Electroosmotic force enhances peristaltic flow when aligned and opposes it when reversed, while thicker electrical double layers and larger couple-stress viscosity oppose flow, and higher Reynolds numbers enhance forward flow under favorable pressure gradients but promote reflux under adverse pressure gradients. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To examine the combined effects of arbitrary Reynolds number, electrokinetic forcing, and couple-stress rheology on velocity profiles, critical reflux, and flow reversal in a symmetric microchannel.

Computational modeling demonstrates how electrokinetic forces and couple-stress rheology govern flow reversal in microchannels, suggesting optimized control for lab-on-a-chip devices.

Key Points

To examine the combined effects of arbitrary Reynolds number, electrokinetic forcing, and couple-stress rheology on velocity profiles, critical reflux, and flow reversal in a symmetric microchannel.
Formulated mass and momentum conservation equations coupled with the Poisson–Boltzmann equation for electroosmotic-peristaltic transport of a couple-stress fluid.
Applied a perturbation method to reduce governing nonlinear partial differential equations into linear ordinary differential equations and solved them numerically using a finite difference scheme in MATLAB.
Electroosmotic force accelerates flow when aligned with peristaltic wave propagation and impedes transport when oriented in reverse.
A thicker electrical double layer increases resistance against electric field-driven flow compared to a thinner layer.
Increasing Reynolds numbers enhances forward flow under favorable pressure gradients but exacerbates reflux under adverse pressure gradients, while higher couple-stress viscosity consistently resists flow.
