Hydrodynamic turbulence and intermittent random fields
In this article, we construct two families of multifractal random vector fields with non symmetrical increments. We discuss the use of such families to model the velocity field of turbulent flows. Short Title. Hydrodynamic turbulence and intermittent random fields
متن کاملLattice models for granular - like velocity fields : Hydrodynamic limit
A recently introduced model describing -on a 1d latticethe velocity field of a granular fluid is discussed in detail. The dynamics of the velocity field occurs through next-neighbours inelastic collisions which conserve momentum but dissipate energy. The dynamics can be described by a stochastic equation in full phase space, or through the corresponding Master Equation for the time evolution of...
متن کاملConfronting Hydrodynamic Simulations Of Relativistic Jets With Data : What Do We Learn About Particles & Fields ?
We review recent relativistic hydrodynamic simulations of jets, and their interpretation in terms of the results from linear stability analysis. These studies show that, interpreted naively, the distribution of synchrotron intensity will in general be a poor guide to the physical state (density and pressure) of the underlying flow, and that even if the physical state can be inferred, it, in tur...
متن کاملIterative Methods for Efficient Generation of Wave Fields in Hydrodynamic Laboratory
Motivated to be applied in the Indonesian Hydrodynamic Laboratory (LHI), we design an iteration scheme for the motion of a wavemaker on one side of a large wave tank in such a way that a desired energy spectrum for the wave field results. Due to imperfections of the mechanical operation of the wavemaker, the mapping from the wavemaker control to the generated wave field in the tank is not known...
متن کاملHydrodynamic instabilities of nematic liquid crystals under A. C. electric fields
2014 We present an extension of the Helfrich theory of hydrodynamic instabilities to the case of alternating electric fields. The electrohydrodynamic effects are described by two coupled equations for the charge density (q) and the local curvature of the molecular alignment (03C8). The relaxation time for q is the dielectric relaxation time 03C4 (~ 10-2 s in typical samples). The relaxation tim...
