考虑稀薄气体在具有空间周期性定常温度分布的两平行平板通道中，通道上周期性地开有一系列沟槽，采用标准的直接模拟蒙特卡罗方法（Bird方法），数值研究了不同Knudsen数和沟槽尺寸时，壁面温度变化引起的流动行为。发现在没有外部施加任何压力梯度的情况下，通过通道诱导稳定的单向流动。讨论了单向流动的泵送效应。
A rarefied gas in a channel of two parallel plane walls with a spatially periodic steady temperature distribution, on which a series of ditches is dug periodically, is considered, and the behavior of a flow induced by the temperature variation on the walls is investigated numerically for various Knudsen numbers and ditch sizes by the standard direct simulation Monte Carlo method (Bird’s method). It is found that a steady one‐way flow is induced through the channel without any pressure gradient being applied externally. The pumping effect owing to the one‐way flow is discussed.
