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 ...

A Reynolds stress model for turbulent flows of viscoelastic fluids
(Taylor & Francis Ltd, 2014)
Employing wind tunnel data to evaluate a turbulent spectral model
(Science Publishing Group, 2016)
In this study, spectra obtained from wind tunnel data are compared with a model that describes observed
atmospheric neutral spectra. The investigation points out that there is a good conformity between both spectra for ...
Characterizing inertial and convective optical turbulence by detrended fluctuation analysis
(Spie, 2013-10)
Atmospheric turbulence is usually simulated at the laboratory by generating convective free flows with hot surfaces, or heaters. It is tacitly assumed that propagation experiments in this environment are comparable to those ...
Numerical simulation of an ethanol turbulent spray flame with RANS and diffusion combustion model
(Heidelberg, 2014-03-06)
A detailed numerical simulation of ethanol
turbulent spray combustion on a rounded jet flame is pre-
sented in this article. The focus is to propose a robust
mathematical model with relatively low complexity sub-
models ...
New developments in isotropic turbulent models for FENE-P fluids
(2018-01-29)
The evolution of viscoelastic turbulent models, in the last years, has been significant due to the direct numeric simulation (DNS) advances, which allowed us to capture in detail the evolution of the viscoelastic effects ...
Modelo simplificado para turbulência na camada limite noturna
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2016-03-08)
The appropriate estimation of turbulent fluxes in very stable conditions is a great challenge
for numerical models that simulate the average behavior of the stable boundary layer.
Although many features of the flow are ...
Transition to quantum turbulence in finite-size superfluids
(WILEY-BLACKWELL, 2011)
A novel concept of quantum turbulence in finite size superfluids, such as trapped bosonic atoms, is discussed. We have used an atomic (87)Rb Bose-Einstein condensate (BEC) to study the emergence of this phenomenon. In our ...
