The Analysis of Rotary Kiln Thermal Characteristics Based on ANSYS and FLUENT

Abstract:

In this paper, the FLUENT finite element software is used to simulation analyze the rotary kiln, kiln gas combustion process and gas-solid coupling effect. The kiln and rotary kiln of gas temperature field is calculated and then imported into the ANSYS software as an initial condition to complete the reconstruction of the temperature field and using the node interpolation method to carry out thermal stress analysis. Through the joint simulation analysis based on FLUENT and ANSYS finite element software, the analysis of rotary kiln combustion process, the heat transfer and the mechanical response of the structure can be implemented under the same condition, making the simulation results of rotary kiln more related to practical operation conditions. The method and results presented have significant theoretical guidance for the research and development of new types of rotary kiln.
