FIG. 7.

Inlet velocity profiles for PPFCs A and D for flow rates yielding uniform flow (left panels) and nonuniform flow (right panels) in each flow chamber. For the left panels low flow rates of 0.0013 ml s⁻¹ (PPFC A) and 0.003 ml s⁻¹(PPFC D) corresponded to shear rates of 6.6 and 2.1 s⁻¹, respectively. For the right panels high flow rates of 1.25 ml s⁻¹ (PPFC A) and 0.33 ml s⁻¹ (PPFC D) corresponded to shear rates of 659 and 219 s⁻¹, respectively.
