physical accuracy scalar transport modeling inhomogeneous turbulence
2016/5/18
Direct numerical simulations of scalar fields produced by uniform and line sources in channel flow are used as the basis for examining the accuracy of random flight and closure models in predicting tu...

Numerical simulation of airfoil flows with a turbulence model
turbulence airfoil incompressible separation openFOAM
2014/5/15
Turbulent flows over AS240 and NACA4412 airfoil were simulated numerically using a two-equation turbulence model named k-ξ model. The predictions of velocity profiles and the pressure coefficient of a...
Long-time properties of MHD turbulence and the role of symmetries
Long-time properties MHD turbulence the role of symmetries Fluid Dynamics
2012/4/20
We investigate long-time properties of three-dimensional MHD turbulence in the absence of forcing and examine in particular the role played by the quadratic invariants of the system and by the symmetr...
Residual Energy in Magnetohydrodynamic Turbulence
Residual Energy Magnetohydrodynamic Turbulence
2011/9/13
There is mounting evidence in solar wind observations and in numerical simulations that kinetic and magnetic energies are not in equipartition in magnetohydrodynamic turbulence. The origin of their mi...
Quasi-static magnetohydrodynamic turbulence at high Reynolds number
Magnetohydrodynamics Quasi-static hypothesis Homogeneous turbulence EDQNM
2011/8/5
Abstract: We analyse the anisotropy of homogeneous turbulence in an electrically conducting fluid submitted to a uniform magnetic field, for low magnetic Reynolds number, in the quasi- static approxim...
Shell model of superfluid turbulence
Shell model superfluid turbulence Kelvin wave cascade phonon emission
2011/8/18
Abstract: Superfluid helium consists of two inter-penetrating fluids, a viscous normal fluid and an inviscid superfluid, coupled by a mutual friction. We develop a two-fluid shell model to study super...
Universality and Scaling Behaviour of Injected Power in Elastic Turbulence in Worm-like Micellar Gel
Universality and Scaling Behaviour Elastic Turbulence Worm-like Micellar Gel
2011/8/18
Abstract: We study the statistical properties of spatially averaged global injected power fluctuations for Taylor-Couette flow of a worm-like micellar gel formed by surfactant CTAT. At sufficiently hi...
Superstatistics as the statistics of quasi-equilibrium states: Application to fully developed turbulence
Superstatistics quasi-equilibrium states developed turbulence
2011/8/18
Abstract: In non-equilibrium states, currents are produced by irreversible processes that take a system toward the equilibrium state, where the current vanishes. We demonstrate, in a general setting, ...
Modeling the transition to turbulence in shear flows
Modeling transition turbulence shear flows
2011/8/5
Abstract: One-dimensional models are presented for transitional shear flows. The models have two variables corresponding to turbulence intensity and mean shear. These variables evolve according to sim...

2011/8/16
Abstract: We report experimental results on the decay of wave turbulence in an elastic plate obtained by stopping the forcing from a stationary turbulent state. In the stationary case, the forcing is ...
