Abstract
Theoretical predictions are presented for the mass flux of particles transported in a turbulent gas flow based on a kinetic theory for dispersed gas-particle flows (Reeks 2021). The results depend critically upon the form of the net turbulent aerodynamic driving force which indicates that the mass flux in inhomogeneous turbulence is both diffusive and convective. Numerical calculations for particle dispersion in a kinematic simulation generated turbulent flow field indicate that this will have a significant influence on the observed build up of particle concentration in turbulent boundary layers and particle pair clustering.
