GAS PARTICLE FLOWS

(i) Fundamental issues: interaction mechanisms; regimes; role of Stokes 
number and particle loading; Lagrangian vs. Eulerian descriptions; governing 
equations.

(ii) Turbulence modelling: relation between turbulence models for the gas and 
solid phases; simple eddy viscosity models; Reynolds stress; LES and DNS 
models.

(iii) Applications: simple laboratory flows; heat exchanger flows; cyclones; 
electrostatic precipitation.
