### Modelling and optimization of a rotary kiln direct

The kiln model is a one-dimensional finite-volume representation of the governing equations for mass and energy conservation, which are approximated by integration over discrete control volumes along the kiln length (i.e. axial slices). The solution of these discrete equations provides the local gas and solids temperatures, and mass fluxes at each
