Stochastic Theory in the Strong Coupling Limit
N. Abedpour, M. D. Niry, A. Bahraminasab +4
The stochastic -theory in dimensions dynamically develops domain wall structures within which the order parameter is not continuous. We develop a statistical theory for th…
Stretching of polymers around the Kolmogorov scale in a turbulent shear flow
Jahanshah Davoudi, Joerg Schumacher
We present numerical studies of stretching of Hookean dumbbells in a turbulent Navier-Stokes flow with a linear mean profile, <u_x>=Sy. In addition to the turbulence features beyon…
Multifractal clustering of passive tracers on a surface flow
G. Boffetta, J. Davoudi, F. De Lillo
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 tw…
Links between dissipation, intermittency, and helicity in the GOY model revisited
John C. Bowman, Charles R. Doering, Bruno Eckhardt +3
High-resolution simulations within the GOY shell model are used to study various scaling relations for turbulence. A power-law relation between the second-order intermittency corre…
Lagrangian tracers on a surface flow: the role of time correlations
Guido Boffetta, Jahanshah Davoudi, Bruno Eckhardt +1
Finite time correlations of the velocity in a surface flow are found to be important for the formation of clusters of Lagrangian tracers. The degree of clustering characterized by…
Closure of two dimensional turbulence: the role of pressure gradients
G. Boffetta, M. Cencini, J. Davoudi
Inverse energy cascade regime of two dimensional turbulence is investigated by means of high resolution numerical simulations. Numerical computations of conditional averages of tra…
