2021-5-4 Void ratio is usually used in parallel with soil porosity (n), which is defined as the ratio of the volume of voids to the total volume of the soil. The posoity and the void ratio are inter-related as follows: e = n /(1-n) and n = e / (1+e) The value of void ratio depends on the consistence and packing of the soil.

Porosity is a concept from the soil research field, also termed soil porosity, representing the total of pore volume as a percentage of soil volume. The pore volume consists of the void volume containing water and the air volume, so porosity reflects the degree of tightness of the soil.

2015-3-1 The average specific cake resistance in the filtration of incompressible cakes is theoretically related to the Sauter mean diameter of particles and the porosity of the filter cake by the Kozeny–Carman equation: (8) α a v = 180 1 − ε ρ s D 3 2 2 ε 3 where ε is the porosity, i.e. the void ratio, of

Porosity, itself, is a rather easy parameter to define—the fraction of void volume over total volume - but certainly not so easy to quantify. The reason is that “void” space expressed in earth materials can span over 8 orders of magnitude in length scale—i.e., nanometer to 10s or even 100s cm or larger.

2018-4-30 The increasing strain versus stress relationships for the particle-void 300-500 μm and the fiber-void were selected for direct comparison (Fig. 5) because these two sets share a similar void-volume value along a plane. The results show a high elasticity for the samples with low nominal porosity and low residual strain at the end of the each cycle.

Porosity. Porosity is the percentage of void volume in a part. Porosity is a controllable function of the raw material and processing techniques. Parts can be produced either with uniform porosity or with variations in porosity (and density) from one section to another to provide different properties.

Porosity, or fractional void volume, is a simple but powerful quantity used in describing porous media. Characterising this very important parameter is vital to understanding key processes that occur in porous media, such as fluid transport. This is because porosity is strongly related to the permeability of porous media

Some of the media falls and impacts the ore particles at the bottom of the mill. The rest of the media cascades and, in the process, creates particle breakage by attrition. The process is continuously repeated as the particles move by mass and volume action through the mill. Dry and wet grinding common.
