Fokker - Planck - Boltzmann equation for dissipative particle dynamics
نویسندگان
چکیده
The algorithm for Dissipative Particle Dynamics (DPD), as modified by Español and Warren, is used as a starting point for proving an H-theorem for the free energy and deriving hydrodynamic equations. Equilibrium and transport properties of the DPD fluid are explicitly calculated in terms of the system parameters for the continuous time version of the model.

Statistical Mechanics of Dissipative Particle Dynamics
The stochastic differential equations corresponding to the updating algorithm of Dissipative Particle Dynamics (DPD), and the corresponding Fokker-Planck equation are derived. It is shown that a slight modification to the algorithm is required before the Gibbs distribution is recovered as the stationary solution to the Fokker-Planck equation. The temperature of the system is then directly relat...
متن کاملThe Maxwell-Boltzmann Distribution is not the Equilibrium on a Hyperboloid
We give a geometric formulation of the Fokker-Planck-Kramer equations for a particle moving on a Lie algebra under the in uence of a dissipative and a random force. Special cases of interest are uid mechanics, the Stochastic Loewner Equation and the rigid body. We nd that the Boltzmann distribution, although a static solution, is not normalizable when the algebra is not unimodular. This is beca...
متن کاملGeneral properties of nonlinear mean field Fokker-Planck equations
Recently, several authors have tried to extend the usual concepts of thermodynamics and kinetic theory in order to deal with distributions that can be non-Boltzmannian. For dissipative systems described by the canonical ensemble, this leads to the notion of nonlinear Fokker-Planck equation (T.D. Frank, Non Linear Fokker-Planck Equations, Springer, Berlin, 2005). In this paper, we review general...
متن کاملOn the accuracy of the Fokker-Planck and Fermi pencil beam equations for charged particle transport.
Electron beam dose calculations are often based on pencil beam formulas such as the Fermi-Eyges formula. The Fermi-Eyges formula gives an exact solution of the Fermi equation. The Fermi equation can be derived from a more fundamental mathematical model, the linear Boltzmann equation, in two steps. First, the linear Boltzmann equation is approximated by the Fokker-Planck equation. Second, the Fo...
متن کاملDissipative Systems and Objective Description: Quantum Brownian Motion as an Example
A structure of generator of a quantum dynamical semigroup for the dynamics of a test particle interacting through collisions with the environment is considered, which has been obtained from a microphysical model. The related master-equation is shown to go over to a Fokker-Planck equation for the description of Brownian motion at quantum level in the long wavelength limit. The structure of this ...
