Estudos numéricos para escoamentos viscoelásticos com a viscosidade dependendo da pressão
(Universidade Estadual Paulista (Unesp), 2018-02-28)
O presente trabalho de mestrado consiste em apresentar uma modelagem para escoamentos isotérmicos viscoelásticos em que a viscosidade varia de acordo com a pressão e estudos numéricos para alguns problemas bidimensionais, ...
A Numerical Study of the FENE-CR Model Applied to a Jet Flow Problem
(Amer Inst Physics, 2013-01-01)
The FENE-CR model is investigated through a numerical algorithm to simulate the time-dependent moving free surface flow produced by a jet impinging on a flat surface. The objective is to demonstrate that by increasing the ...
Reynolds and Weissenberg numbers in viscoelastic flows
(Elsevier B.V., 2021-06-01)
One of the greatest challenges in performing numerical simulations of viscoelastic flow is how to choose the model parameters in order to be able to achieve quantitative agreement with experimental measurements in benchmark ...

Influence of non-Newtonian blood flow models on drug deposition in the arterial wall
(2019-12-01)
In this paper, we investigate the influence of non-Newtonian blood flow models on drug diffusion from a coronary drug-eluting-stent (DES). We consider the Oldroyd-B, Phan-Thien-Tanner (PTT) and Giesekus viscoelastic models ...
NUMERICAL INVESTIGATION OF THREE DIMENSIONAL VISCOELASTIC FREE SURFACE FLOWS: IMPACTING DROP PROBLEM
(Int Center Numerical Methods Engineering, 2014-01-01)
This work presents a numerical investigation of three dimensional viscoelastic free surface flows. In particular, using two different numerical methodologies, we have simulated a typical free-surface benchmark flow problem: ...
Numerical simulation of drop impact and jet buckling problems using the eXtended Pom-Pom model
(Elsevier B.V., 2012-02-01)
This work presents numerical simulations of two fluid flow problems involving moving free surfaces: the impacting drop and fluid jet buckling. The viscoelastic model used in these simulations is the eXtended Pom-Pom (XPP) ...
