“…However, the influence of the gas phase in the core-flow on pipelines and connections is still not well defined, and further studies are needed to ensure the efficiency of the technique in this physical situation. The tests of the related phenomena that emerged in connections were evaluated by Wang et al [9], Andrade et al [10], Andrade et al [11], Andrade et al [12], Andrade et al [13] and Crivelaro et al [14]. Particularly with reference to reduction of pressure drop in flow, Brauner et al [15] has reported a correlation applied to heavy-oil/water two-phase flow in an annular flow pattern.…”

Este artigo tem como objetivo estudar o escoamento trifásico água – óleo pesado – ar em dutos horizontais, utilizando a técnica “core annular flow”. O modelo matemático utilizado foi o não-homogêneo, numa abordagem Euleriana – Euleriana. Considerou-se o modelo de mistura para tratar os termos de transferência de momento interfacial entre as fases contínuas (água e óleo pesado) e o modelo de partícula para tratar os termos de transferência de momento interfacial entre as fases dispersa e contínua (ar e óleo pesado). Todas as simulações foram realizadas utilizando o Software CFX versão 11. Resultados dos campos de pressão e fração volumétrica das fases e queda de pressão no duto são apresentados e comparados com dados experimentais. Verificou-se que a modelagem matemática utilizada foi adequada, apresentado erro máximo com relação aos dados experimentais de queda de pressão de 7,3%, demonstrando a eficiência da técnica core-flow para o transporte trifásico de água - óleo pesado – ar.

Review of Core Annular Flow

et al. 2023

With the increasing demand for heavy oil, core annular flow (CAF) is an economical method to transport heavy oil, and many researchers have explored the energy-saving aspects of the CAF method. This paper presents a review of CAF energy saving and factors affecting CAF energy saving. Among them, the energy saving of CAF mainly concerns the changes in pressure drop and drag reduction efficiency; the factors affecting the energy saving of CAF mainly concern the problem of stability, the issue of restarting the pipeline system, the impact of a nozzle, the impact of fouling on the flow in the pipe, and the problem of oil–water accumulation. The aim of this paper is to provide a reference for the practical application of CAF in heavy oil transportation.
