研究了具有相互作用粒子的台球系统中的热整流现象。这种相互作用引起台球对外部热力学梯度的局部动力学响应。为了解释这种动力学效应,我们研究了一个不对称台球的粒子和能量反射系数的稳定状态。这使我们能够获得表达式的参数空间中的区域,预计大的热整流。我们的结果得到了广泛的数值模拟证实。
We study the thermal rectification phenomenon in billiard systems with interacting particles. This interaction induces a local dynamical response of the billiard to an external thermodynamic gradient. To explain this dynamical effect we study the steady state of an asymmetric billiard in terms of the particle and energy reflection coefficients. This allows us to obtain expressions for the region in parameter space where large thermal rectifications are expected. Our results are confirmed by extensive numerical simulations.
