Numerical investigation of three dimensional viscoelastic free surface flows: impacting drop problem
(International Association for Computational Mechanics (IACM)European Community on Computational Methods in Applied Sciences (ECCOMAS)Barcelona, 2014-07-20)
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 ...
Linear viscoelasticity of styrenic block copolymers-clay nanocomposites
(SPRINGER, 2008)
In this work, the rheological behavior of block copolymers with different morphologies (lamellar, cylindrical, spherical, and disordered) and their clay-containing nanocomposites was studied using small amplitude oscillatory ...
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 ...
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
(Int Center Numerical Methods Engineering, 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 ...
Influence of temperature, calcium and sucrose concentration on viscoelastic properties of prosopis chilensis seed gum and nopal mucilage dispersions
(Wiley, 2018-07)
Viscoelastic properties of two nontraditional hydrocolloid dispersions were evaluated. Prosopis chilensis seed gum was evaluated based on temperature (5-80 degrees C) and added CaCl2 (0.07%), whereas nopal mucilage was ...
On the creep behavior of carbon/epoxy non-crimp fabric composites
(2018-01-01)
The use of composites in structural applications requires the study of specific properties to ensure that these materials are safe and an excellent option to replace some metals, for example. In the present study, vacuum ...
Influence of temperature on optimum viscoelastic absorbers in cubic nonlinear systems
(Sage Publications Ltd, 2014-11)
Recently, viscoelastic materials have been widely used for vibration control due to their efficacy and flexibility in real engineering problems. Their use as constitutive parts of dynamic vibration absorbers requires the ...
