Multiscaling and Structure Functions in Turbulence: An Alternative Approach
نویسندگان
چکیده
We propose an alternative formulation of structure functions for the velocity field in fully developed turbulence. Instead of averaging moments of the velocity differences as a function of the distance, we suggest to average moments of the distances as a function of the velocity difference. This is like an “inverted” structure function, with a different statistics. On the basis of shell model calculations we obtain a new multiscaling spectrum.

The Varieties of Dynamic Multiscaling in Fluid Turbulence
We show that different ways of extracting time scales from time-dependent velocity structure functions lead to different dynamic-multiscaling exponents in fluid turbulence. These exponents are related to equal-time multiscaling exponents by different classes of bridge relations which we derive. We check this explicitly by detailed numerical simulations of the GOY shell model for fluid turbulenc...
متن کاملThe Universality of Dynamic Multiscaling in Homogeneous, Isotropic Turbulence
We systematise the study of dynamic multiscaling of time-dependent structure functions in different models of passive-scalar and fluid turbulence. We show that, by suitably normalising these structure functions, we can eliminate their dependence on the origin of time at which we start our measurements and that these normalised structure functions yield the same linear bridge relations that rela...
متن کاملDynamic multiscaling in magnetohydrodynamic turbulence.
We present a study of the multiscaling of time-dependent velocity and magnetic-field structure functions in homogeneous, isotropic magnetohydrodynamic (MHD) turbulence in three dimensions. We generalize the formalism that has been developed for analogous studies of time-dependent structure functions in fluid turbulence to MHD. By carrying out detailed numerical studies of such time-dependent st...
متن کاملMultiscaling of cosmic microwave background radiation
The multiscaling features of structure functions of cosmic microwave background (CMB) radiation have been studied using the new data available with the resolution of the order of a degree (combined QMAP and Saskatoon CMB radiation maps). It is shown that the scaling exponents of the CMB structure functions in the angular scale interval 0.9–4◦ are nearly identical to those of universal velocity ...
متن کاملDynamic multiscaling in two-dimensional fluid turbulence.
We obtain, by extensive direct numerical simulations, time-dependent and equal-time structure functions for the vorticity, in both quasi-Lagrangian and Eulerian frames, for the direct-cascade regime in two-dimensional fluid turbulence with air-drag-induced friction. We show that different ways of extracting time scales from these time-dependent structure functions lead to different dynamic-mult...
