Universal dissipation scaling for nonequilibrium turbulence.
It is experimentally shown that the nonclassical high Reynolds number energy dissipation behavior, C(ε)≡εL/u(3)=f(Re(M))/Re(L), observed during the decay of fractal square grid-generated turbulence (where Re(M) is a global inlet Reynolds number and Re(L) is a local turbulence Reynolds number) is also manifested in decaying turbulence originating from various regular grids. For sufficiently high...
متن کاملUniversal Finite-size-scaling Functions
The idea of universal finite-size-scaling functions of the Ising model is tested by Monte Carlo simulations for various lattices. Not only regular lattices such as the square lattice but quasiperiodic lattices such as the Penrose lattice are treated. We show that the finite-size-scaling functions of the order parameter for various lattices are collapsed on a single curve by choosing two nonuniv...
متن کاملUniversal scaling law of electrical turbulence in the mammalian heart.
Many biological processes, such as metabolic rate and life span, scale with body mass (BM) according to the universal law of allometric scaling: Y = aBM(b) (Y, biological process; b, scaling exponent). We investigated whether the temporal properties of ventricular fibrillation (VF), the major cause of sudden and unexpected cardiac death, scale with BM. By using high-resolution optical mapping, ...
متن کاملScaling of Low-Order Structure Functions in Homogeneous Turbulence.
High-resolution direct numerical simulation data for three-dimensional Navier-Stokes turbulence in a periodic box are used to study the scaling behavior of low-order velocity structure functions with positive and negative powers. Similar to high-order statistics, the low-order relative scaling exponents exhibit unambiguous departures from the Kolmogorov 1941 theory and agree well with existing ...
متن کاملLagrangian Structure Functions in Turbulence: Scaling Exponents and Universality
In this paper, the approach for investigation of asymptotic (Re→∞) scaling exponents of Eulerian structure functions (J. Schumacher et al, New. J. of Physics 9, 89 (2007). ) is generalized to studies of Lagrangian structure functions in turbulence. The novel ”bridging relation” based on the derived expression for the fluctuating, moment-order dependent dissipation time τη,n, led to analytic exp...
