Rheological Behavior of W/O Emulsion of Water-Heavy Oil System and Friction Loss Reduction Methods for its Flow in a Pipe

Port and Airport Research Institute      052-04-03

December, 2013

Oil Spill Response Group
Isamu FUJITA,Yoshitaka MATSUZAKI

Spilled oil takes sea water as small droplets inside it and forms W/O emulsion due to mixing effect of turbulence of ocean wave. T...
