Turbophoresis
Encyclopedia
Turbophoresis is the tendency for particles to migrate in the direction of decreasing turbulence
level. The principle tends to segregate particles entrained in high velocity gases axially toward the wall region.
Dasgupta et al., (1997) demonstrated that the non-uniform cross-sectional particle distribution observed during high-velocity flow of gas-particle mixtures through a vertical duct is indeed driven by turbophoresis.
Turbulence
In fluid dynamics, turbulence or turbulent flow is a flow regime characterized by chaotic and stochastic property changes. This includes low momentum diffusion, high momentum convection, and rapid variation of pressure and velocity in space and time...
