Numerical Modelling and Study of Combustion Behaviour of Rotary Cement Kiln Using Computational Fluid Dynamics

Halefom Kidane

Rotary  Cement kiln is one of the key equipment in cement industry used to convert calcineous raw meal to cement clinkers .Now days  Computational fluid dynamics   (CFD) is main tool used for conducting researches in different fields in absence of experimental tools or laboratories this paper aims understanding of the flow behaviour what is takes place inside the Cement rotary kilns using Computational fluid dynamics   .  Both the Primarily and Secondary types of methodologies were used to reach to final point of the research . The Computational fluid dynamics    model used in this program solves the Reynolds-averaged Naiver-Stokes (RANS) with K-∈ turbulence model. The main  thermal parameters  which are basic for combustion were investigated and confirmed resulted was obtained.
