Um estudo das equações de Navier-Stokes com condições de fronteira de tipo Navier
(2019)
Neste trabalho estudamos uma série de resultados relacionados as equações bidimensionais de Navier - Stokes para fluidos incompressíveis em domínios limitados, sujeitos a condição de fronteira de tipo Navier de fricção.O ...
Stresses of PTT, Giesekus, and Oldroyd-B fluids in a Newtonian velocity field near the stick-slip singularity
(Amer Inst Physics, 2017-12-01)
We characterise the stress singularity of the Oldroyd-B, Phan-Thien-Tanner (PTT), and Giesekus viscoelastic models in steady planar stick-slip flows. For both PTT and Giesekus models in the presence of a solvent viscosity, ...

Global lipschitz continuous solutions for a linear damped p-system
(Bogotá - Ciencias - Maestría en Ciencias - MatemáticasDepartamento de MatemáticasUniversidad Nacional de Colombia - Sede Bogotá, 2020-11-04)
In this proposal we present an alternative point of view for the mathematical treatment
of a linearly damped p-system through a variant of the vanishing viscosity method and the
use of the theory of compensated compactness. ...
