Thermodynamics of a time dependent and dissipative oval billiard: a heat transfer and billiard approach

Edson D. Leonel, Marcus Vinicius Camillo Galia, Luiz Antonio Barreiro, Diego F. M. Oliveira

摘要:

我们研究了一些统计性质的行为的平均平方速度-因此温度-为一个合奏的经典粒子在台球的边界是时间依赖性的。我们假设粒子与台球边界的碰撞是非弹性的,导致平均平方速度在足够长的时间内达到稳态动力学。稳态的描述是通过使用两种不同的方法:(i)由傅立叶定律激发的热传递,(ii)使用数值模拟和理论描述的台球动力学。

英文摘要:

We study some statistical properties for the behavior of the average squared velocity -- hence the temperature -- for an ensemble of classical particles moving in a billiard whose boundary is time dependent. We assume the collisions of the particles with the boundary of the billiard are inelastic leading the average squared velocity to reach a steady state dynamics for large enough time. The description of the stationary state is made by using two different approaches: (i) heat transfer motivated by the Fourier law and, (ii) billiard dynamics using either numerical simulations and theoretical description.
