Pressure loss in core-annular flow: Modeling, experimental investigation and full-scale experiments
(Elsevier Science BvAmsterdamHolanda, 2009)
Caracterização do escoamento bifásico líquido-gás em golfadas em dutos verticais
(Universidade Tecnológica Federal do ParanáCuritibaBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2014-08-12)
Gas-liquid two-phase flows occur in many branches of industry. The flow can occur in different patterns depending on the flow rates, the properties of the phases and inclination of the tube. Slug flow is the most common ...
Simulação computacional de escoamentos verticais ascendentes gás-líquido no padrão disperso com transferência de calor
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2018-12-04)
In this work a study was carried out on gas-liquid vertical upwards two-phase flows, considering the homogeneous flow hypothesis on dispersed bubble pattern. The primary objective is to verify the influence that an external ...
Two-phase flow frictional pressure drop prediction in helical coiled tubes
(Pergamon-Elsevier Science Ltd, 2020-12)
Based on the construction of different experimental databases, the frictional pressure drop in helical tubes for single-phase and water-steam two-phase flow was analyzed empirically. The aim of the present study is to ...
Stability analysis of core-annular flow and neutral stability wave number
(JOHN WILEY & SONS INC, 2008)
A general transition criterion is proposed in order to locate the core-annular flow pattern in horizontal and vertical oil-water flows. It is based on a rigorous one-dimensional two-fluid model of liquid-liquid two-phase ...
