摘要研究了屈服应力流体液滴在相同材料薄膜上的表面张力和重力作用下的铺展。一旦液滴内部的驱动应力下降到屈服应力以下,液滴就收敛到最终的平衡形状。标度法的最终半径和补充浅液滴的渐近分析。此外,使用流体体积法和正则化的本构关系的数值模拟,并与Carbopol的水溶液的实验,提出。
Abstract 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.
