Simulação do perfil axial de pressão na coluna riser de um leito fluidizado circulante
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilPrograma de Pós-Graduação em Engenharia MecânicaUTFPR, 2015-12-11)
Gas-solid flows in circulating fluidized bed systems are very common in industrial processes, being a research subject in recent years because of its highly complex nature. The study of parameters related to the hydrodynamics ...
Sensor capacitivo multieletrodo para monitoramento de nível em separadores multifásicos
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Elétrica e Informática IndustrialUTFPR, 2019-12-17)
With the increasing production demand of the oil industry, it is more and more necessary to develop and improve systems, technologies and processes within their various stages. Among them, one important process is the ...
Análise experimental de um distribuidor para escoamento bifásico líquido-gás
(Universidade Tecnológica Federal do ParanáCuritibaBrasilCurso de Engenharia MecânicaUTFPR, 2018-12-10)
Liquid-gas two-phase flows are widely found in nature and in industrial processes, especially in the chemical, oil and nuclear industry. In many industrial facilities, whether for economic interests, to meet environmental ...
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 ...
Avaliação de um modelo algébrico térmico para a simulação de escoamentos bifásicos líquido-gás em golfadas com predição de mudança de fase e correção de propriedades físico-químicas
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia MecânicaUTFPR, 2016-12-05)
The correct modelling of the two-phase liquid-gas flow in pipes under slug flow pattern is a challenge to several industries, and the oil & gas companies stand out among them. Identifying this flow pattern and quantifying ...
Stability and conductivity of proppant packs during flowback in unconventional reservoirs: A CFD–DEM simulation study
(Elsevier Science, 2021-06)
We present simulations using a coupled Computational Fluid Dynamics–Discrete Element Method (CFD–DEM) approach for a slurry of millimeter-sized particles in water which is squeezed between two walls and then made flow out ...
