Abstract

The transport technique called Core Annular Flow (CAF) consists on the formation of an annular flow of a viscous liquid with low viscosity as water on the boundary of a flow of a viscous liquid as oil, cre-ating a biphasic system of a duct flow. Through this technique is possible to decrease the consumed power on the transport of a high viscosity fluid. The present work had the purpose to scale out, develop and study the cargo loss of a liquid vertical separation device to create the CAF, simulating e.g. a petroleum well. The device was built by a hydrocyclone and a liner forcing the formation of the CAF technique. Beside the men-tioned advantages of the Core Annular Flow, the literature is poor of data concerning the formation of this vertical duct flow and the optimization of the technique variables.
