论文摘要

液态空气界面处的自动驱动纳米流体流是一种非直觉现象。这种流动行为不仅是由经典的压力差或蒸发驱动的。根据纳米流体孔的位置,我们可以观察到流动和混乱的行为。在本文中,我们研究了液态空气界面处的受限纳米孔系统的非线性动力学。相互作用物种之间的有限范围相互作用通过系统的相应临界速度进行量化。这是使用有限元方法可视化的,并使用Landau标准进行了数学分析。我们发现,由于通过纳米流通孔的运输而形成了玻色 - 因斯坦样冷凝物。我们表明,具有以上直径低于100 nm的纳米流体孔的系统会产生高度非线性和复杂的系统。相关的经典系统与现有量子机械系统的近似在基本层面上泄露了新的结果和更正。我们解释了系统在液相中振荡的冷凝物的形成。探索了系统的特定边界附近的高速度,振荡的突然消失及其对蒸发的依赖性。经典力学对量子力学的前景的过渡给量子纳米流体学领域的进一步研究留下了几个开放问题。

Self-driven nanofluidic flow at the liquid-air interface is a non-intuitive phenomenon. This flow behaviour was not driven by classical pressure difference or evaporation only. Depending on the position of the nanofluidic pore we can observe flow and no-flow with chaotic behaviour. In this paper, we study the nonlinear dynamics of a confined nanopore system at the liquid-air interface. The finite-range interactions between the interacting species are quantified with a corresponding critical velocity of the system. This is visualised using the finite element method and analysed mathematically with the Landau criterion. We found the formation of Bose-Einstein-like condensates due to the transport through nanofluidic pores. We show that systems with more than one nanofluidic pore with a sub-100 nm diameter create a highly nonlinear and complex. The approximation of relevant classical systems to existing quantum mechanical systems divulges new results and corrections at a fundamental level. We explain the formation of oscillating condensate within the system in the liquid phase. The high velocity near the specific boundaries of the system, the sudden disappearance of oscillations, and its dependence on evaporation are explored. This transition of classical mechanics with the outlook of quantum mechanics leaves several open questions for further investigation in the field of quantum nanofluidics.
