A continuously differentiable upwinding scheme for the simulation of fluid flow problems
(Elsevier B.V., 2012-05-01)
This paper deals with the numerical solution of complex fluid dynamics problems using a new bounded high resolution upwind scheme (called SDPUS-C1 henceforth), for convection term discretization. The scheme is based on TVD ...

Modelagem dinâmica do escoamento de um sistema de elevação por plunger lift
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia MecânicaTecnologia de Materiais; Projetos Mecânicos; Termociências, 2012-04-18)
A critical problem in mature gas wells is the liquid loading. As the reservoir pressure decreases,
gas superficial velocities decreases and the drag exerted on the liquid phase may become
insufficient to bring all the ...
Projeto conceitual de scramjets para voo hipersônico e análise comparativa da influência do número de rampas no desempenho do motor
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2023-07-14)
Maintaining hypersonic flight has always been a major challenge for aerospace engineering,
such as designing structures that can withstand high pressures and temperatures, or
propulsive elements capable of generating ...
Assessment and redesign of a compressed air system in a steel foundry
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2018-05-14)
Compressed air systems are regarded as one of the main utilities in industry; however, their continuous operation is not only inefficient but expensive. A case study on the energy efficiency of a large and complex compressed ...
Seismic wave attenuation and dispersion due to wave-induced fluid flow in rocks with strong permeability fluctuations
(Acoustical Society of America Institute of Physics, 2013-06)
Oscillatory fluid movements in heterogeneous porous rocks induced by seismic waves cause dissipation of wave field energy. The resulting seismic signature depends not only on the rock compressibility distribution, but also ...
Modelo fenomenológico para compressores alternativos
(Universidade Federal de Minas GeraisUFMG, 2014-10-03)
This paper presents the development of a mathematical model of a reciprocating compressor operating at steady state, implemented in the computer program Engineering Equation Solver (EES). The main input variables of the ...
