Nucleation of bubbles in a stretched Lennard-Jones liquid located between two flat smooth solid walls has been investigated by the molecular dynamics method. A dense monomolecular liquid layer is maintained on the wall surface during near-wall boiling-up at the moment of bubble origin. The centers of bubbles are located mainly at a distance of (1.5–3) molecular diameters from the walls. The nucleation rate in the near-wall layer is two orders of magnitude higher than in a homogeneous liquid. Liquid boiling-up in the presence of smooth wettable walls proceeds by the mechanism of homogeneous nucleation, independently of the bubble formation location.

Lennard-Jones过热液体在具有坚固光滑壁的通道中的沸腾

通过分子动力学方法研究了位于两个平坦光滑的固体壁之间的拉伸的Lennard-Jones液体中气泡的成核作用。在气泡产生时的近壁沸腾过程中，在壁表面上保持了致密的单分子液体层。气泡的中心主要位于距壁（1.5–3）分子直径的距离处。近壁层中的成核速率比均匀液体中的成核速率高两个数量级。在存在光滑的可湿壁的情况下，液体沸腾是通过均相成核机制进行的，与气泡的形成位置无关。
