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 ...
Vertical dispersion of Lagrangian tracers in fully developed stably stratified turbulence
(American Physical Society, 2019-01-29)
We study the effect of different forcing functions and of the local gradient Richardson number Rig on the vertical transport of Lagrangian tracers in stably stratified turbulence under the Boussinesq approximation and ...
A Reynolds stress model for turbulent flows of viscoelastic fluids

Emergence of intermittent structures and reconnection in MHD turbulence
(CUP, 2010-09)
In recent analyses of numerical simulation and solar wind dataset, the idea that the magnetic discontinuities may be related to intermittent structures that appear spontaneously in MHD turbulence has been explored in ...
Turbulence comes in bursts in stably stratified flows
(American Physical Society, 2014-04)
There is a clear distinction between simple laminar and complex turbulent fluids; however, in some cases, as forthe nocturnal planetary boundary layer, a stable and well-ordered flow can develop intense and sporadic bursts ...
Spatiotemporal detection of Kelvin waves in quantum turbulence simulations
(American Physical Society, 2015-12)
We present evidence of Kelvin excitations in space-time resolved spectra of numerical simulations of quantum turbulence. Kelvin waves are transverse and circularly polarized waves that propagate along quantized vortices, ...
CH and C2 radicals characterization in natural gas turbulent diffusion flames
(2005-04-01)
This paper reports the construction of an axisymmetric nonpremixed piloted jet burner, with well-defined initial and boundary conditions, known as the Delft burner, to assess turbulence-chemistry interaction in non-premixed ...

Modelagem e simulação do escoamento em um Venturi
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2014-08-25)
The main objective in this work is the behavior analysis of a turbulent flow in a Venturi. The Venturi used had circular cross section, the turbulent flow was considered steady and the fluid flow inside the Venturi is ...
On the interactión of ocean waves and turbulence
(2010)
The interaction of ocean waves and turbulence is a fundamental process in the ocean. Understanding and prediction of wind-wave generation, propagation, breaking, non-linear interactions and extreme wave development are ...
