在这项工作中，低粘度液滴在饱和蒸汽中的部分润湿表面上的早期动力学的格子Boltzmann数值模拟研究。研究了凝结输运对铺展过程的影响。我们观察到，冷凝电流导致的轻微过饱和的液体蒸汽附近的动态润湿弯月面的运动，并影响扩展动力学。我们的研究结果表明，为了正确地捕捉初始动力学的惯性传播的相对挥发性的液滴，重要的是要考虑到通过冷凝在接触线附近的蒸汽输送。与实验数据的自发润湿液滴的直接定性和定量比较。
In this work, the early time dynamics of low-viscosity liquid drops spreading in their saturated vapor on partially wetting surfaces are investigated by lattice Boltzmann numerical simulations. Attention is paid to the effect of vapor transport through condensation on the spreading process. We observe that the condensation current resulting from the slight supersaturation of the liquid vapor near the dynamic wetting meniscus contributes to the motion and affects the spreading dynamics. Our results indicate that, in order to properly capture the initial dynamics of inertial spreading of a relatively volatile liquid drop, it is important to account for the vapor transport through condensation in the immediate vicinity of the contact line. A direct qualitative and quantitative comparison with experimental data of spontaneously wetting liquid drops is presented.
