Two different experimental methods for determining the threshold of particle motion as a function of geometrical properties of the bed from laminar…
![Accurate Determination of the Equilibrium Surface Tension Values with Area Perturbation Tests](https://jovecdn2.ccindex.cn/files/thumbs/59818_t.png)
We demonstrate two robust protocols for determining the equilibrium surface tension (EST) values with area perturbation tests. The EST values should…
