The scaling in the overlap region of turbulent wall-bounded flows has long been the source of
controversy, and until recently this controversy could not be addressed because measurements
did n...
A NEW MEAN VELOCITY SCALING FOR TURBULENT BOUNDARY LAYERS
TURBULENT BOUNDARY LAYERS MEAN VELOCITY SCALING
2014/12/30
A new scaling, originally developed for the mean velocity
profile of turbulent pipe flow, was extended to the case of zero
pressure gradient turbulent boundary layers. At low Reynolds
numbers, the ...
Longitudinal and transverse velocity scaling exponents from merging of the Vortex filament and Multifractal models
Longitudinal and transverse velocity scaling exponents merging of the Vortex filament Multifractal models Fluid Dynamics
2012/4/20
We suggest a simple explanation of the difference between transverse and longitudinal scaling exponents observed in experiments and simulations. Based on the Vortex filament model and Multifractal con...
The Kibble-Zurek Problem: Universality and the Scaling Limit
Kibble-Zurek nonequilibrium quench adiabatic
2012/2/27
Near a critical point, the equilibrium relaxation time of a system diverges and any change of control/thermodynamic parameters leads to non-equilibrium behavior. The Kibble-Zurek problem is to determi...
Distributional fixed point equations for island nucleation in one dimension: a retrospective approach for capture zone scaling
Gap size distribution capture zone distribution
2012/2/27
The distribution of the capture zones of point islands nucleated in one dimension are considered using a retrospective view, providing an alternative perspective on why scaling occurs in this continuo...
Universality and Scaling Behaviour of Injected Power in Elastic Turbulence in Worm-like Micellar Gel
Universality and Scaling Behaviour Elastic Turbulence Worm-like Micellar Gel
2011/8/18
Abstract: We study the statistical properties of spatially averaged global injected power fluctuations for Taylor-Couette flow of a worm-like micellar gel formed by surfactant CTAT. At sufficiently hi...
We study the morphology of watersheds in two and three dimensional systems subjected to different degrees of spatial correlations. The response of these objects to small, local perturbations is also i...
Scaling laws prediction from a solvable model of turbulent thermal convection
Turbulent flows, convection and heat transfer Turbulence simulation and modeling
2011/8/31
A solvable turbulent model is used to predict both the structure of the boundary layer and the scaling laws in thermal convection. The transport of heat depends on the interplay between the thermal, v...
Scaling in large Prandtl number turbulent thermal convection
Turbulent fiows convection and heat transfer Turbulence simulation and modeling
2011/9/13
We study the scaling properties of heat transfer Nu in turbulent thermal convection at large Prandtl number Pr using a quasi-linear theory. We show that two regimes arise, depending on the Reynolds nu...
Momentum transport and torque scaling in Taylor-Couette flow from an analogy with turbulent convection
Convection and heat transfer Taylor-Couette flow
2011/8/31
We generalize an analogy between rotating and strati ed shear ows. This analogy is summarized in Table 1. We use this analogy in the unstable case (centrifugally unstable ow v.s. convection)to compute...
Anomalous scaling and generic structure function in turbulence
turbulence Symmetry and conservation laws
2011/8/30
We discuss on an example a general mechanism of apparition of anomalous scaling in scale invariant systems via zero modes of a scale invariant operator. We discuss the relevance of such mechanism in t...
