Numerical study of the square-root conformation tensor formulation for confined and free-surface viscoelastic fluid flows
(2016-12-01)
We present a numerical study of a stabilization method for computing confined and free-surface flows of highly elastic viscoelastic fluids. In this approach, the constitutive equation based on the conformation tensor, which ...

Three-dimensional transient complex free surface flows: Numerical simulation of XPP fluid
(2013-05-01)
In this paper we present a finite difference MAC-type approach for solving three-dimensional viscoelastic incompressible free surface flows governed by the eXtended Pom-Pom (XPP) model, considering a wide range of parameters. ...

Numerical assessment of mass conservation on a MAC-type method for viscoelastic free surface flows
(2012-12-01)
A numerical study of mass conservation of MAC-type methods is presented, for viscoelastic free-surface flows. We use an implicit formulation which allows for greater time steps, and therefore time marching schemes for ...

A numerical study of the Kernel-conformation transformation for transient viscoelastic fluid flows
(Elsevier B.V., 2015-12-01)
This work presents a numerical application of a generic conformation tensor transformation for simulating highly elastic flows of non-Newtonian fluids typically observed in computational rheology. In the Kernel-conformation ...
Numerical predictions of viscoelastic flows with an algebraic extra-stress model
(2014-01-01)
Numerical simulation of viscoelastic flows using Phan-Thien-Tanner (PTT)[1] differential constitutive equation, and an algebraic extra-stress model (AESM) proposed by G. Mompean [2] are presented in this work. In order to ...
