- •
We investigate shear banded flow of DJS fluids under various conditions.
- •
Under shear banding, we capture the expected & unique shear-stress/strain path.
- •
The uniquely selected stress-strain path is affected by various fluid properties.
- •
The stress–strain path is also affected by geometric conditions and fluid injection.
- •
Our results provide useful information on viscoelastic fluid flows in microchannels.
