What is meant by porosity?

1a : the quality or state of being porous. b : the ratio of the volume of interstices of a material to the volume of its mass. 2 : pore.

How do you calculate Voidage of a bed?

The term voidage is normally used to refer to the tiny spaces between particles in a powder or granulated material like sand. The actual calculation of voidage is simple: it is the amount of empty space divided by the total volume.

What is the relationship between sphericity and Voidage?

It is found that as the sphericity decreases, the bed voidage increases. Increasing the particle density and initial bed height causes the voidage to decrease due to the strong compression in the bed. The decrease in the voidage can lead to a decrease in the minimum fluidization velocity.

Which is the correct definition of the term voidage?

[′vȯid·ij] (materials) The volume of the voids in a sample of powder divided by its overall volume (that is, the total volume occupied by the voids and the solid material).

What is the difference between voidage and gap?

Experimental values for the voidage fraction of binary mixtures of differently shaped particles have been extracted from literature.

How is voidage defined in non Newtonian flow?

R.P. Chhabra, J.F. Richardson, in Non-Newtonian Flow in the Process Industries, 1999 Voidage, e, is defined as the fraction of the total volume which is free space available for the flow of fluids, and thus the fractional volume of the bed occupied by solid material is (1 − ε).
