Development of phase fraction and flow rate meter in two-phase flows based on electrical impedance and pressure drop measurements
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Elétrica e Informática IndustrialUTFPR, 2019-08-30)
Multiphase flows are present in several areas of industry, such as in petroleum production in which oil, gas and water flow through pipelines. The knowledge of flow parameters – e.g. phase fractions, phase distribution and ...
Flow-through photometric sensor for the determination of cadmium at toe nanogram per millilitre level
(1993)
A sensor for the determination of cadmium based on retention of the Cdl4″ complex on a QAE Sephadex resin located in the flow-cell of a conventional photometric detector and on subsequent complex displacement reaction with ...
Pulsating Flow of an Ostwald-De Waele Fluid between Parallel Plates
(MDPI, 2020)
The flow between two parallel plates driven by a pulsatile pressure gradient was studied analytically with a second-order velocity expansion. The resulting velocity distribution was compared with a numerical solution of ...
Gradient flows, second-order gradient systems and convexity
(Society for Industrial and Applied Mathematics Publications, 2018)
We disclose an interesting connection between the gradient flow of a C

Structural dynamic analysis of vertical bars of turbine protection trashracks of hydroelectric plant
(2016-01-01)
Trashracks of hydroelectric plants are very important equipment because they are responsible for protection of hydraulic turbines against impact of floating bodies. These structures are basically constituted by horizontal ...
Instrumentação baseada em redes de Bragg em fibra ótica para a monitoração da vazão de fluídos através do uso da termometria
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Elétrica e Informática Industrial, 2010-04-09)
In this work we inferred a fluid flow seeping from a cooper pipe through thermometers scheme in different flows, through the use of optical sensors based on temperature Bragg Gratings written in optical fiber (FBG). We ...
Simulador de escoamento multifásico em poços de petróleo (SEMPP)
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia do PetróleoPesquisa e Desenvolvimento em Ciência e Engenharia de Petróleo, 2013-02-07)
The multiphase flow occurrence in the oil and gas industry is common throughout fluid
path, production, transportation and refining. The multiphase flow is defined as flow
simultaneously composed of two or more phases ...
Técnicas de separação do escoamento em pequena bacia rural
(Universidade Federal de Santa MariaBrasilEngenharia AmbientalUFSMPrograma de Pós-Graduação em Engenharia AmbientalCentro de Tecnologia, 2018-05-23)
The observed flow in a hydrograph is composed by the surface flow, subsurface flow and groundwater flow due to their trajectory and time of detention. The separation of these components is a necessity to understand ...
