We study a liquid-gas coexistence system in a container under gravity with heat flow in the direction opposite to gravity. By molecular dynamics simulation, we find that the liquid buoys up and continues to float steadily. The height at which the liquid floats is determined by a dimensionless parameter related to the ratio of the temperature gradient to gravity. We confirm that supercooled gas remains stable above the liquid. We provide a phenomenological argument for explaining the phenomenon from a simple thermodynamic assumption.

重力作用下液-气共存中的热致液体悬停

我们研究了重力作用下容器中的液气共存系统，热流方向与重力相反。通过分子动力学模拟，我们发现液体浮起并持续稳定地漂浮。液体漂浮的高度由与温度梯度与重力之比相关的无量纲参数确定。我们确认过冷气体在液体上方保持稳定。我们提供了一个现象学论证，用于从简单的热力学假设来解释该现象。
