New prediction methods for CO2 evaporation inside tubes: Part I - A two-phase flow pattern map and a flow pattern based phenomenological model for two-phase flow frictional pressure drops
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
An updated flow pattern map was developed for CO2 on the basis of the previous Cheng-Ribatski-Wojtan-Thome CO2 flow pattern map [1,2] to extend the flow pattern map to a wider range of conditions. A new annular flow to ...
Interfacial-tension-force Model For The Wavy Stratified Liquid-liquid Flow Pattern Transition: The Usage Of Two Different Approaches
(Amer Inst PhysicsMelville, 2016)
Two-phase flow patterns and pressure drop inside horizontal tubes containing twisted-tape inserts
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
This paper presents an experimental study on two-phase flow patterns and pressure drop of R134a inside a 15.9 mm ID tube containing twisted-tape inserts. Experimental results were obtained in a horizontal test section for ...
Foam flow of oil-refrigerant R12 mixture in a small diameter tube
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2006-12)
This paper presents an experimental investigation of the mineral oil ISO VG10-refrigerant R12 mixture flow with foam formation in a straight horizontal 3.22 mm ID, 6.0 m long tube. An experimental apparatus was designed ...
Experimental investigation on liquid-liquid-gas flow: Flow patterns and pressure-gradient
(Elsevier Science BvAmsterdamHolanda, 2009)
On the measurement of the mass flow rate of horizontal two-phase flows in the proximity of the transition lines which separates two different flow patterns
(Elsevier Sci LtdOxfordInglaterra, 2008)
Natural modes of the two-fluid model of two-phase flow
(American Institute of Physics, 2021-03)
A physically based method to derive well-posed instances of the two-fluid momentum transport equations from first principles is presented. The basic tools used in this endeavor are the variational principles of field theory, ...
Flow evolution of a metallic slurry during thixoextrusion of an automotive valve
(2004-12-01)
The aim of this work is to characterize a metallic slurry (Al-4.5%Cu) flow during thixoforming of an automotive valve. The necessary globular structure was obtained by first inoculating the alloy with TIBAL (5%Ti, 1%B, Al ...
Estudo experimental da influência da pressão no escoamento bifásico gás-líquido em golfadas em dutos horizontais
(Universidade Tecnológica Federal do ParanáCuritibaBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2013-04-23)
Two-phase liquid-gas flow are commonly found in industrial uses, mainly in oil and gas, chemical and nuclear industries. Different geometrical configurations, known as flow pattern, are found in two-phase flows. They occur ...
