Abstract

Abstract

The main purpose is to show that the gravity term of the segregation-mixing equation of fine mono-disperse particles in a fluid can be derived from elementary physics(i.e.first principles).The derivation of the gravity-driven flux of particles leads to the simplest case of the Richaidson and Zald correlation.Stokes velocity also naturally appears from the physical parameters of the particles and fluid by means of derivation only,for the first time.This derivation fmm first principle physics has never been presented before.It is applicable in small concentrations of fine particles
- gravity segregation,
- Kynch batch flux,
- first principles derivation,
- Burger-type equation
