Journal ArticleDOI
An overview of heavy oil properties and its recovery and transportation methods
TL;DR: In this article, the main properties of high-viscosity crude oils, as well as compares traditional and emergent methods for their recovery and transportation, are discussed to highlight the oil properties that affect their flowability in the processes of recovery and pipeline transportation.
Journal ArticleDOI
Modeling aspects of oil–water core–annular flows
TL;DR: In this article, several aspects of core-annular flow modeling are analyzed and discussed in the light of experimental data, and criteria for existence of stable core flow are proposed, which show the essential role played by interfacial tension.
Journal ArticleDOI
Flow Patterns in Heavy Crude Oil-Water Flow
Antonio Carlos Bannwart,Oscar Mauricio Hernandez Rodriguez,Carlos H. M. de Carvalho,Isabela S. Wang,Rosa M. O. Vara +4 more
TL;DR: In this article, an experimental study on the flow patterns formed by heavy crude oil (initial viscosity and density 488 mPa s, 925.5 kg/m 3 at 20°C) and water inside vertical and horizontal 2.84-cm-i.d. pipes was performed.
Journal ArticleDOI
Experimental study of gas-liquid two-phase flow patterns within centrifugal pumps impellers
William Monte Verde,Jorge Luiz Biazussi,Natache do Socorro Dias Arrifano Sassim,Antonio Carlos Bannwart +3 more
TL;DR: In this paper, high-speed imaging was used as a technique to visualize the flow inside a centrifugal pump impeller and to correlate the topological distribution of the phases of pump performance.
Journal ArticleDOI
Contact angle measurements and wetting behavior of inner surfaces of pipelines exposed to heavy crude oil and water
TL;DR: In this paper, the role of the oil polar components on the wetting of such surfaces by crude oils through contact angle measurements in systems containing heavy oil/aqueous phase/metallic surfaces was investigated.
