Numerical analysis of mixed electroosmotic/pressure driven flow of power-law fluids in microchannels and micropumps

▶ EO micropumping of pseudoplastics generates higher flow rates rather than dilatants. ▶ Higher flow rate and pressure rise for pseudoplastics with higher zeta potentials. ▶ Higher flow rate and pressure rise for pseudoplastics with thinner EDLs. ▶ No increase in flow rate and pressure rise of dilatants with increase in zeta potential. ▶ Thinner EDLs do not increase the flow rate and pressure rise of dilatants.
