A Reynolds stress model for turbulent flows of viscoelastic fluids
(Taylor & Francis Ltd, 2013-12-01)
A second-order closure is developed for predicting turbulent flows of viscoelastic fluids described by a modified generalised Newtonian fluid model incorporating a nonlinear viscosity that depends on a strain-hardening ...
Time decorrelation in isotropic magnetohydrodynamic turbulence
(Europhysics Letters, 2011-12)
Time decorrelation in isotropic incompressible magnetohydrodynamic (MHD) turbulence is studied using three-dimensional numerical simulation. Eulerian and wavenumber-dependent correlation functions are obtained. Scaling ...
Instabilities; shocks and turbulence in space and astrophysical plasmas
(Asociación Argentina de Astronomía, 2018-10)
The dynamics of plasmas pervading the interplanetary and interstellar medium are often described within the frame of magnetohydrodynamics (MHD), which involves the coupling between flows and magnetic fields. This theoretical ...
Numerical simulation of a radial diffuser turbulent airflow
(Elsevier B.V., 2007-06-15)
In the present work are presented results from numerical simulations performed with the ANSYS-CFX (R) code. We have studied a radial diffuser flow case, which is the main academic problem used to study the flow behavior ...

Development of a low-Reynolds-number k-ω model for FENE-P fluids
(2013-01-01)
A low-Reynolds-number k-ω model for Newtonian fluids has been developed to predict drag reduction of viscoelastic fluids described by the FENE-P model. The model is an extension to viscoelastic fluids of the model for ...
