热泳作为持续随机游走

Thermophoresis as persistent random walk

A. V. Plyukhin

摘要:

在一个简单的模型中,一个连续的随机行走的粒子在一个维度上移动,速度在V和-V之间波动。如果V与布朗粒子的热速度相关联,并允许位置相关,该模型很容易占粒子的漂移沿温度梯度,并恢复传统的热泳理论的基本结果。

英文摘要:

In a simple model of a continuous random walk a particle moves in one dimension with the velocity fluctuating between V and -V. If V is associated with the thermal velocity of a Brownian particle and allowed to be position dependent, the model accounts readily for the particle's drift along the temperature gradient and recovers basic results of the conventional thermophoresis theory.
