Eulerian and Lagrangian studies in surface flow turbulence

- J. R. Cressman, J. Davoudi, W. Goldburg, J. Schumacher
- Physics
- 1 May 2004

Experimental and numerical studies of turbulent fluid motion in a free surface are presented. The flow is realized experimentally on the surface of a tank filled with water stirred well below the… Expand

TLDR

Stretching of polymers around the Kolmogorov scale in a turbulent shear flow

- J. Davoudi, J. Schumacher
- Physics
- 3 January 2006

We present numerical studies of stretching of Hookean dumbbells in a turbulent Navier-Stokes flow with a linear mean profile, ⟨ux⟩=Sy. In addition to the turbulence features beyond the viscous… Expand

Taylor's frozen-flow hypothesis in Burgers turbulence.

Multifractal clustering of passive tracers on a surface flow

- G. Boffetta, J. Davoudi, F. D. Lillo
- Physics
- 24 October 2005

We study the anomalous scaling of the mass density measure of Lagrangian tracers in a compressible flow realized on the free surface on top of a three-dimensional flow. The full two-dimensional… Expand

Mean profiles for a passive scalar in wall-bounded flows from symmetry analysis

- N. Marati, J. Davoudi, C. Casciola, B. Eckhardt
- Mathematics
- 1 January 2006

Based on the symmetry properties of the equations for a passive scalar in turbulent wall-bounded flows we derive the symmetry invariant mean profiles of the scalar. In a unifying framework we… Expand

Links between dissipation, intermittency, and helicity in the GOY model revisited

- J. Bowman, C. Doering, B. Eckhardt, J. Davoudi, M. Roberts, J. Schumacher
- Physics

Fluctuation of Mass Flux in a Cloud-Resolving Simulation with Interactive Radiation

- J. Davoudi, N. McFarlane, T. Birner
- Environmental Science, Physics
- 1 February 2010

Abstract It was shown by Craig and Cohen that fluctuations of cumulus clouds under homogeneous large-scale forcing satisfy the Gibbs canonical ensemble in a strict radiative–convective equilibrium… Expand

Theoretical Model for the Kramers-Moyal Description of Turbulence Cascades

- J. Davoudi, M. R. R. Tabar
- Physics
- 22 February 1999

We derive the Kramers-Moyal equation for the conditional probability density of velocity increments from the theoretical model recently proposed by V.Yakhot [Phys.Rev.E {\bf 57}, 1737 (1998)] in the… Expand
