General description

硅油是一种液体基硅氧烷,其是甲基硅油体系的一部分。它的粘度为500 cSt,并取决于链长分布。折射率约为1.402,介电强度约为14 kV/mm。随着粘度的增加,它的表面张力也会趋于增加。

We study the permeability of quasi-two-dimensional porous structures of randomly placed overlapping monodisperse circular and elliptical grains. Measurements in microfluidic devices and lattice Boltzmann simulations demonstrate that the permeability is determined by the Euler characteristic of the conducting phase. We
