Physical Model of Hydrodynamic Turbulence

The Physics of Fluids, 1969
A model for statistically isotropic homogeneous turbulence in an incompressible fluid is constructed, representing the turbulence as a superposition of individual vortex sheets. Each vortex sheet moves in the velocity field of the other sheets which have larger scale.

Supercoiled DNA: Hydrodynamic model

Journal of Theoretical Biology, 1974
Two and three parameter theories have been introduced to describe the sedimentation behavior of the twisted DNA molecule compared to nontwisted DNA molecule. In the first model, the sedimentation equations have been developed using two parameters, namely, the excluded volume and the chain stiffness.

Toy Model of Hydrodynamic Fluctuations

Physical Review Letters, 2006
We study hydrodynamic fluctuations in an ideal gas. Because one is interested in thermodynamic properties of small volume elements, Einstein's theory of equilibrium fluctuations in large systems is insufficient. A toy model of correlated fluctuations in neighboring small cells leads us to the distinction of biased and unbiased momentum densities ...

Models of intermittency in hydrodynamic turbulence

Physical Review Letters, 1990
Summary: A heuristic model for evolution of probability distribution (PDF) of transverse velocity gradient \(s\) in incompressible Navier-Stokes turbulence is distilled from an analytical closure for Burgers turbulence. At all Reynolds numbers \(\mathcal R\), the evolved PDF is \(\propto| s| ^ {-1/2}\exp(-\text{const}\times| s| /\langle s^ 2\rangle^ {1/
