Turbulence via intermolecular potential: Viscosity and transition range of the Reynolds number
Rafail V. Abramov
Turbulence in fluids is an ubiquitous phenomenon, characterized by spontaneous transition of a smooth, laminar flow to rapidly changing, chaotic dynamics. In 1883, Reynolds experim…
Turbulence in large scale two-dimensional balanced hard sphere gas flow
Rafail V. Abramov
In recent works we developed a model of balanced gas flow where the momentum equation possesses an additional mean field forcing term, which originates from the hard sphere interac…
Formation of turbulence via an interaction potential
Rafail V. Abramov
In a recent work, we proposed a hypothesis that the turbulence in gases could be produced by particles interacting via a potential - for example, the interatomic potential at short…
Turbulent energy spectrum via an interaction potential
Rafail V. Abramov
For a large system of identical particles interacting by means of a potential, we find that a strong large scale flow velocity can induce motions in the inertial range via the pote…
A theory of average response to large jump perturbations
Rafail V. Abramov
A key feature of the classical Fluctuation Dissipation theorem is its ability to approximate the average response of a dynamical system to a sufficiently small external perturbatio…
The effect of the Enskog collision terms on the steady shock structure in a hard sphere gas
Rafail V. Abramov
In this work we study the effect of the Enskog collision terms on the steady shock transitions in the supersonic flow of a hard sphere gas. We start by examining one-dimensional, n…
