Exponential velocity tails in a driven inelastic Maxwell model.
نویسندگان
چکیده
The problem of the steady-state velocity distribution in a driven inelastic Maxwell model of shaken granular material is revisited. Numerical solution of the master equation and analytical arguments show that the model has bilateral exponential velocity tails [P(v) approximately e(-|v|/sqrt[D])], where D is the amplitude of the noise. Previous study of this model predicted Gaussian tails [P(v) approximately e(-av(2))].

Driven inelastic Maxwell models with high energy tails.
The solutions of the homogeneous nonlinear Boltzmann equation for inelastic Maxwell models, when driven by different types of thermostats, show, in general, overpopulated high energy tails of the form approximately exp(-ac), with power law tails and Gaussian tails as border line cases. The results are compared with those for inelastic hard spheres, and a comprehensive picture of the long time b...
متن کاملAsymptotic solutions of the nonlinear Boltzmann equation for dissipative systems
Analytic solutions F (v, t) of the nonlinear Boltzmann equation in ddimensions are studied for a new class of dissipative models, called inelastic repulsive scatterers, interacting through pseudo-power law repulsions, characterized by a strength parameter ν, and embedding inelastic hard spheres (ν = 1) and inelastic Maxwell models (ν = 0). The systems are either freely cooling without energy in...
متن کاملThe Boltzmann Equation for Driven Systems of Inelastic Soft Spheres
We study a generic class of inelastic soft sphere models with a binary collision rate g that depends on the relative velocity g. This includes previously studied inelastic hard spheres (ν = 1) and inelastic Maxwell molecules (ν = 0). We develop a new asymptotic method for analyzing large deviations from Gaussian behavior for the velocity distribution function f (c). The framework is that of the...
متن کاملRandom inelasticity and velocity fluctuations in a driven granular gas.
We analyze the deviations from Maxwell-Boltzmann statistics found in recent experiments studying velocity distributions in two-dimensional granular gases driven into a non-equilibrium stationary state by a strong vertical vibration. We show that in its simplest version, the "stochastic thermostat" model of heated inelastic hard spheres, contrary to what has been hitherto stated, is incompatible...
متن کاملExperimental observations of non-equilibrium distributions and transitions in a 2D granular gas
A large number (∼10,000) of uniform stainless steel balls comprising less than one layer coverage on a vertically shaken plate provides a rich system for the study of excited granular media. Viewed from above, the horizontal motion in the layer shows interesting collective behavior as a result of inelastic particleparticle collisions. Clusters appear as localized fluctuations from purely random...
