ABSTRACT:
A viscous liquid core in less viscous liquid annulus pipe flow with less viscous liquid in viscous liquid emulsions is created without the injection of additional less viscous liquid by establishing a sufficiently high shear rate, but not to exceed a certain value, for a sufficiently long time in pipe flow to break the emulsion and create a less viscous liquid rich zone near the pipe wall, thus reducing the flow pressure drop.
