Leidenfrost固体与棘轮表面之间的热驱动流动
Thermally-driven flows between a Leidenfrost solid and a ratchet surface
摘要：
基于Boltzmann方程的数值解，研究了棘轮表面上热驱动流动对Leidenfrost固体推进的意义。与以前的分析相比，发现没有建立显着的热蠕变流。相反，流动模式主要是由热边缘和热应力滑移流，后者被指向相反的热蠕变流。然而，在总的热诱导流只作出微小的贡献，由压力驱动的流动，由于升华固体的棘轮表面上的莱顿弗罗斯特固体的推进占主导地位。
英文摘要：
The significance of thermally-driven flows for the propulsion of Leidenfrost solids on a ratchet surface is studied based on a numerical solution of the Boltzmann equation. In contrast to a previous analysis, it is found that no significant thermal creep flow is established. Instead, the flow pattern is dominated by thermal edge and thermal-stress slip flow, the latter being directed opposite to thermal creep flow. However, in total thermally-induced flows only make a minor contribution to the propulsion of Leidenfrost solids on ratchet surfaces which is dominated by the pressure-driven flow due to the sublimating solid.
