The planar contraction/expansion multiple-stream flow instability in microchannels and mixing performance of two-dissimilar polyethylene-oxide (PEO) fluids were examined. Experimental results indicate that fluid viscosity and low fluid inertia were insufficient to induce flow instability. The viscoe...
