To investigate the relationship between impact velocity and particle-size distribution
, the present study uses experimental and DEM simulation data.

This work contributes to the selection of soil PSD models to describe the soil particle-size distribution
curve which can be used to estimate the hydraulic properties and to compare and convert the different soil texture classification systems.
Almost all process engineers actually require particle-size distributions
based on the mass or volume of particles.

As the permeability k is an intrinsic property of the specimen, which is related to the pore structure of granular rock mass, the seepage velocity v should be the function of particle-size distribution
parameter n and the porosity [phi]:
It has sloping limits for clay content that accord with field texture descriptions based on soil behaviour, and it provides a smoother transition in particle-size distribution
between neighbouring classes.
We also note that currently there are particle-size analysers used in Australian laboratories that can provide 10-15 size classes, which allows for a continuous particle-size distribution
. However, in order to use this information effectively, we need to parameterise the distribution; a parsimonious yet flexible function that can accommodate multi-modal size distributions is required.
The normal N351 particle-size distribution
is tight and homogeneous, whereas the skew of the hypothetical carbon black blends are exaggerated toward the particle size distribution of the two component grades.
Snowhite high-purity, dry-ground calcium carbonates in tightly controlled particle-size distribution
reportedly allow optimized filler levels.
Low-cost Camel-Fil for SMC/BMC provides particle-size distribution
for high loading and/or low viscosity.
Each produces pigments with different structures, degrees of aggregation, and primary particle-size distributions
. Pigments can also be after-treated to improve performance.
