A two-phase solver for complex fluids: Studies of the Weissenberg effect
(Elsevier B.V., 2016-09-01)
In this work a new two-phase solver is presented and described, with a particular interest in the solution of highly elastic flows of viscoelastic fluids. The proposed code is based on a combination of classical Volume-of-Fluid ...
High-pressure phase equilibria of systems carbon dioxide + n-eicosane and propane + n-eicosane
(Elsevier Science, 2009-10)
In this work we investigated the phase equilibrium behavior of the binary asymmetric systems propane (C3) + n-eicosane (C20) and carbon dioxide (CO2) + n-eicosane (C20). We used a variable-volume view cell for obtaining ...
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 ...
Characterization of simple magnetorheological fluids with potential application in engineering
(International Journal of Engineering and Innovative Technology, 2014-09)
In this work, the authors wonder if it is possible to easily create affordable and simple-made magnetorheological fluids with interesting properties in order to design speed control devices. The focus is on simplicity and ...
Complexity in Faraday experiment with viscoelastic fluid
(World Scientific, 2007-12)
A systematic experimental study of the Faraday instability in viscoelastic fluid is presented. We have used a shear thinning polymer solution in which the elastic effects are predominant within our work range. We have ...
Unified lagrangian formulation for elastic solids and incompressible fluids. application to fluid-structure interaction problems via the PFEM
(Elsevier Science Sa, 2008-03)
We present a general Lagrangian formulation for treating elastic solids and quasi/fully incompressible fluids in a unified form. The formulation allows to treat solid and fluid subdomains in a unified manner in fluid–structure ...
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 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 ...
