论文摘要
研究了在表面张力下的扩散和在同一材料的薄膜上的一滴屈服液体的重力。一旦液滴内部的驱动应力落在屈服应力以下，液滴会收敛到最终平衡形状。最终半径显示了缩放定律，并与浅液滴的渐近分析相辅相成。此外，提出了使用流体量方法和正则本构定律的数值模拟，并提出了具有水溶液溶液的实验。
The spreading under surface tension and gravity of a droplet of yield-stress fluid over a thin film of the same material is studied. The droplet converges to a final equilibrium shape once the driving stresses inside the droplet fall below the yield stress. Scaling laws are presented for the final radius and complemented with an asymptotic analysis for shallow droplets. Moreover, numerical simulations using the volume-of-fluid method and a regularized constitutive law, and experiments with an aqueous solution of Carbopol are presented.
