2. Sedimentation
2.1 Motion of a solid particle in a stationary fluid
Consider a spherical particle, with density ρ g , diameter d g , sedimentation velocity U, relative to the fluid of density ρ f and viscosity η in which it settles.
We define a grain Reynolds criterion :
The grain is slowed down in its movement by the fluid and a drag force F appears which depends on...
