Distributed generation modelling for unbalanced three-phase power flow calculations in smart grids
(2011-05-31)
Distributed Generators (DG) are generally modeled as PQ or PV buses in power flow studies. But in order to integrate DG units into the distribution systems and control the reactive power injection it is necessary to know ...
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, ...
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 ...
Flow through porous media with applications to heap leaching of copper ores

Técnicas avançadas para análise de escoamento bifásico gás-líquido em golfadas
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Elétrica e Informática Industrial, 2011-07-08)
Characterization of two-phase flows is important for monitoring and control of many industrial processes. In this regard, the proposed paper uses ultrasonic techniques, wire-mesh sensor and high-speed videometry to extract ...

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 ...
