Probability distributions of turbulent energy.

Probability density functions (PDFs) of scale-dependent energy fluctuations, P[deltaE(l)] , are studied in high-resolution direct numerical simulations of Navier-Stokes and incompressible magnetohydrodynamic (MHD) turbulence. MHD flows with and without a strong mean magnetic field are considered. For all three systems it is found that the PDFs of inertial range energy fluctuations exhibit self-...

Universality of Probability Distributions among Two-dimensional Turbulent Ows

We study statistical properties of two-dimensional turbulent ows. Three systems are considered: the Navier-Stokes equation, surface quasi-geostrophic ow, and a model equation for thermal convection in the Earth's mantle. Direct numerical simulations are used to determine 1-point uctuation properties. Comparative study shows universality of probability density functions (PDFs) across diierent ty...

Derivation of turbulent energy of fiber suspensions

The energy equation for turbulent flow of fiber suspensions was derived in terms of second order correlation tensors. Fiber motion of turbulent energy including the correlation between pressure fluctuations and velocity fluctuations was discussed at two points of flow field, at which the correlation tensors were the functions of space coordinates, distance between two points, and time.

Conflations of Probability Distributions

The conflation of a finite number of probability distributions P1, . . . , Pn is a consolidation of those distributions into a single probability distribution Q = Q(P1, . . . , Pn), where intuitively Q is the conditional distribution of independent random variables X1, . . . ,Xn with distributions P1, . . . , Pn, respectively, given that X1 = · · · = Xn. Thus, in large classes of distributions ...
