Singular boundaries in the forward chapman-kolmogorov differential equation

Author(s): Hierro, Juan , Dopazo, C.
Description: The forward Chapman-Kolmogorov differential equation is used to model the time evolution of the Probability Density Function of fluctuations. This equation may be restricted to either Master, Fokker-Planck or Liouville equations. A derivation of the Liouville equation with possible singular boundary...

Scalar probability density function mixing models need not comply with the linearity and independence hypothesis

Author(s): Hierro, Juan , Dopazo, C.
Description: In a mixture of scalar fields undergoing diffusive processes governed by Fick's law, the concentration at each point evolves linearly in the concentrations at all points and independently from the other concentrations, when one considers a finite differences integration of their evolution equations....

Fourth-order statistical moments of the velocity gradient tensor in homogeneous, isotropic turbulence

Author(s): Hierro, Juan , Dopazo, C.
Description: A compact expression of fourth-order statistical moments of the velocity gradient tensor in homogeneous, isotropic, incompressible turbulence is obtained as a function of its invariants and of generic components of the velocity gradient. This single, compact expression is in full agreement with the ...

Local geometry of isoscalar surfaces

Description: PACS:47.51.+a, 47.27.Gs, 47.27.tb , An inert dynamically passive scalar in a constant density fluid forced by a statistically homogeneous field of turbulence has been investigated using the results of a 2563 grid direct numerical simulation. Mixing characteristics are characterized in terms of either p...

Supply-cost curves for geographically distributed renewable-energy resources

Description: The supply-costcurves of renewable-energy sources are an essential tool to synthesize and analyze large-scale energy-policy scenarios, both in the short and long terms. Here, we suggest and test a parametrization of such curves that allows their representation for modeling purposes with a minimal se...
