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. ...

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 ...
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 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 ...

Determination of the numerical parameters of a continuous damage model for the structural analysis of clay brick masonry
(Universidade Federal de São Carlos (UFSCar), Dept Engenharia Materials, 2012-12-01)
Models based on the continuous damage theory present good responses in representing the nonlinear behavior of reinforced concrete structures with loss of strength and stiffness of the material. However, damage theory is ...
Precisão de plantas planialtimétricas em função do posicionamento de pontos em irradiadas de campo
(2006-01-01)
The present experiment aimed to study the influence of point positioning in an irradiated field to produce a planialtimetric plant. A planialtimetric evaluation was carried out in a 14-acre experimental area with well-defined ...
