Effects of surface roughness and wall confinement on bluff body aerodynamics at large-gap regime
(2021-08-01)
A purely Lagrangian vortex method is employed to investigate turbulent flows past a rough circular cylinder under moving wall effect at large-gap regime, namely h*/d* = 0.45 and 0.80 (h* establishes the gap height between ...
Estudo da dinâmica de bolhas de gás isoladas em um rotor centrífugo
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2019-12-10)
Electrical submersible pump using centrifugal pumps is currently one of the most commonly used artificial lifting techniques in the oil industry. However due to the presence of gas in some oil reservoirs, pumps can operate ...
Experimental evaluation of cuttings displacement by the drill bit-drill string assembly in a horizontal well
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2021-11-29)
Not only the oil production but also the well depths have been increasing over the years in Brazil. As a consequence, new techniques and technologies have been required by the industry in order to be able to extract the ...
Investigação numérica da sedimentação de partícula em fluido de lei de potência utilizando o método lattice – Bolzmann
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2018-06-29)
Sedimentation of individual particles immersed in non-Newtonian fluid is of great industrial interest. Specifically in the oil and gas industry, cuttings generated from the drilling process must be constantly removed in ...
