Equações de Navier-Stokes: aspectos físicos e solução fraca em espaços de Sobolev
(Universidade Federal de Santa MariaBRMatemáticaUFSMPrograma de Pós-Graduação em Matemática, 2008-12-10)
In this work, based on the Law of conservation of mass and the Newton s second Law, we deducted the equations of Navier-Stokes for the uncompressing fluids. Then we have developed in a detailed way the varying form of ...
O teorema de Cauchy em equações de Navier-Stokes
(Universidade Federal de Santa MariaBRMatemáticaUFSMPrograma de Pós-Graduação em Matemática, 2013-03-08)
This work presents the Cauchy's theorem in its classical form, and aims to weaken their
hypotheses, providing a more advantageous use in continuum mechanics. The methodology
is axiomatic, that is, basic concepts are ...
Explorando a conexão entre a mecânica dos fluidos e a teoria cinética
(Sociedade Brasileira de Física, 2016-04-05)
The understanding of the physical properties of fluids enabled several technological advances. For instance, it is worth mentioning the production of aircrafts, ships and cars with optimized design, which reduce the co-called ...
Evaluación de la segregación estática en concreto autoconsolidable utilizando un dispositivo basado en la ley de Stokes
(2011-06-02)
Abstract.
In the present study the displacement of a spherical particle, to simulate the segregation of
coarse aggregate in self-compacting concrete, was evaluated. For this purpose, a Stokes' Law
Based Device (SLBD), ...
A stability result for the identification of a permeability parameter on navier–stokes equations
(IOP, 2022)
In this work, we present a stability result for the inverse problem of recovering a smooth scalar permeability parameter given by the Brinkman's law applied to the steady Navier-Stokes equations from local observations of ...

Pulsatile flow between two coaxial porous cylinders with slip on inner cylinder.
(2011-10-13)
A fully developed, axisymmetric, pulsatile motion of an incompressible Newtonian fluid,under the action of an oscillatory pressure gradient, has been considered in this work. The fl ow is assumed to take place in the ...
