• Modeling of Oxidation Process of Coal Tar Pitch in ...

    In this paper, a threedimensional numerical model has been developed to study the process of oxidative weight increment of coal tar pitch in a rotating kiln. Based on the twofluid method, the gas phase is modeled by realizable kε turbulent model and the solid phase is modeled by kinetic theory of granular flow. The dense gassolid flow, heat transfer, and oxidation reaction for the bed and ...
