Overview

Experimental study demonstrates passive chaotic mixing in low-Reynolds-number microchannels, indicating efficient fluid homogenization without turbulent flow.

Key Points

To develop an efficient passive method for mixing steady, pressure-driven fluid streams within microchannels under low Reynolds number conditions.
Fabricated microchannels with bas-relief surface patterns on the floor using planar lithography.
Introduced steady, pressure-driven fluid streams under laminar flow conditions to evaluate passive mixing dynamics.
Required channel mixing length scaled logarithmically with the Péclet number rather than linearly.
Axial hydrodynamic dispersion was reduced relative to conventional smooth microchannels.
