WebMay 1, 1995 · Figure 1 shows a typical measured dependence of porosity on d/H. Obviously, for both loose and dense packings, decreasing the thickness of particles, i.e. the increase of d/H ratio, will increase the porosity. This effect, though it varies with the did ratio, was found in all our tests involving more than 30 e (d/H, d/D)-d/H relations (Zou and ... WebJul 27, 2016 · Abstract.
