A series of discrete element simulations of single-particle crushing test were conducted on the porous particle modeled as an assembly of boned elementary blocks. …
Pore Size vs. Particle Size in HPLC Columns
In HPLC, a narrow particle size distribution is desirable. A particle size distribution of dp ± 10% would mean that 90% of the particles fall between 9 and 11 µm for an average 10 µm dp packing. The …
What is the relationship between total pore space and …
Is there any relationship between particle size and pore space? Porosity varies depending on particle size and aggregation. It is greater in clayey and organic soils than in sandy soils. A large number of small particles in a volume of soil produces a large number of soil pores. Fewer large particles can occupy the same volume of soil so there ...
