Initially, such studies were limited to simple flow configurations as pointed out by Hoomans, however, Chu and Yu demonstrated that the method could be applied to a complex flow configuration consisting of a fluidized bed, conveyor belt and a cyclone. Similarly, Zhou et al. applied the CCDM approach to the complex geometry of fuel-rich/lean burner for pulverised coal combustion in a plant and Chu et al. modelled the complex flow of air, water, coal and magnetite particles of different sizes in a dense medium cyclone (DMC).
