Numerical solution of the eXtended Pom-Pom model for viscoelastic free surface flows
(ELSEVIER SCIENCE BV, 2011)
In this paper we present a finite difference method for solving two-dimensional viscoelastic unsteady free surface flows governed by the single equation version of the eXtended Pom-Pom (XPP) model. The momentum equations ...
DNS and LST stability analysis of Oldroyd-B fluid in a flow between two parallel plates
(Elsevier B.V., 2019-05-01)
Several flows of practical interest are of viscoelastic fluids and it is desirable to know if these flows are in a laminar or turbulent state. In this paper, the laminar-turbulent transition is studied in which the convection ...
Understanding thixotropic and antithixotropic behavior of viscoelastic micellar solutions and liquid crystalline dispersions. I. The model
(1999)
A simple model consisting of the Upper Convected Maxwell constitutive equation and a kinetic equation for destruction and construction of structure, first proposed by Fredrickson in 1970, is used here to reproduce the ...

Application of the PTT Model to Axisymmetric Free Surface Flows
(Amer Inst Physics, 2013-01-01)
This work is concerned with numerical simulation of axisymmetric viscoelastic free surface flows using the Phan-Thien-Tanner (PTT) constitutive equation. A finite difference technique for solving the governing equations ...
Análise de estabilidade de escoamentos do fluido viscoelástico Giesekus
(Universidade Estadual Paulista (Unesp), 2018-08-02)
O presente trabalho investiga a transição laminar-turbulenta devido a ondas de Tollmien-Schlichting para o escoamento de Poiseuille incompressível, bidimensional, de um fluido viscoelástico, utilizando a equação constitutiva ...

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 ...
Rheology of cetyltrimethylammonium p-toluenesulfonate-water system. 3. Nonlinear viscoelasticity
(1999)
The nonlinear viscoelastic behavior of the cetyltrimethylammonium p-toluenesulfonate (CTAT)-water system is investigated in steady and unsteady shear flow as a function of surfactant concentration and temperature. A ...
