DOI: 10.1016/j.ces.2018.09.027
Abstract: Abstract The penetration time of hydrophilic micron particles during the submergence process is experimentally studied by using a high-speed camera. The effects of impact velocity (0.5 m/s ≤ up0 ≤ 1.48 m/s), surface tension (44.3 mN/m ≤ γ ≤ 73.9 mN/m) and dynamic viscosity (1.31 mPa·s ≤ μ ≤ 2.13 mPa·s) on the… read more here.
