POM spheres with a = 8 mm (d 1/ 2/ 3 = 5/7/10 mm) with a A = 1 mm and b A = 0.8 mm as
well as c a = 5.6 mm (d 1/ 2/ 3 = 3/5/7 mm) with A = 1 mm as well as (d–f) dry and wet (M
= 0/2.5/5%) glass spheres with a = 8 mm (d 1/ 2/ 3 = 5/7/10 mm) with d A = 1 mm and e A =
0.8 mm as well as f a = 5.6 mm (d 1/2/3 = 3/5/7 mm) with A = 1 mm. All results are obtained
by experimental investigations (results are averaged over 15 experiments) and DEM simulations,
respectively. Reprint with permission from [29]
