Mixing layer manipulation experiment: From open-loop forcing to closed-loop machine learning control
(Springer, 2015-01)
Open- and closed-loop control of a turbulent mixing layer is experimentally performed in a dedicated large scale, low speed wind-tunnel facility. The flow is manipulated by an array of fluidic micro-valve actuators integrated ...
Aproximação numérica de escoamento de fluidos power-law utilizando o código livre MFIX
(Universidade do Vale do Rio dos Sinos, 2013-01-31)
Non-Newtonian fluids exhibit nonlinear relationship between the shear stress and the shear rate, that is, its viscosity is not constant. They are present in nature (blood, sludge) as well as many industrial products are ...

The competing roles of extensional viscosity and normal stress differences in complex flows of elastic liquids
(KOREAN SOC RHEOLOGY, 2009)
In various attempts to relate the behaviour of highly-elastic liquids in complex flows to their rheometrical behaviour, obvious candidates for study have been the variation of shear viscosity with shear rate, the two normal ...
Aplicação do método lagrangiano SPH (Smoothed Particle Hydrodynamics ) para a solução do problema das cavidades
(Universidade Federal do Espírito SantoBRPoluição do Ar, Recursos Hídricos, Saneamento AmbientalPrograma de Pós-Graduação em Engenharia AmbientalUFES, 2013-08-19)
Neste estudo foi aplicado do método numérico, sem malhas, baseado em partículas, denominado SPH (Smoothed Particles Hydrodynamics). E um código numérico na linguagem computacional FORTRAN foi utilizado para solucionar as ...
Roll wave prediction model of Herschel–Bulkley fluids evolving on porous bottom
(2021-09-01)
The media have been reporting natural disasters frequently associated with climate change. When it comes to mudflows, the impact is substantial, especially on highly vulnerable communities. Under appropriate conditions ...
Velocity and temperature profiles, wall shear stress and heat transfer coefficient of turbulent impinging jets
(ElsevierBrasilNúcleo Interdisciplinar de Dinâmica dos Fluidos, 2019)
Modelagem matemática de esteiras em desenvolvimento temporal utilizando o método pseudoespectral de Fourier
(Universidade Federal de UberlândiaBRPrograma de Pós-graduação em Engenharia MecânicaEngenhariasUFU, 2016)
Stability analysis of shear banding flow with the BMP model
(2007)
The Bautista-Manero-Puig (BMP) model, consisting of the upper-convected Maxwell constitutive equation coupled to a kinetic equation that takes into account structural changes induced by flow, predicts the basic features ...
