can be implemented under the same condition, making the simulation results of rotary kiln more related to practical operation conditions.
In addition to the differences inthe file formats, the grids model used by these two software are always inconsistent.Therefore, in order to carry out the thermal stress calculation, the CFD grid should be mapped to the FEA meshes,Moreover, upon the analysis of thecombustion processandgas-solidcouplingeffect by CFD, theanalogvalue of theobtained rotary kilntemperature fieldneeds to be transformed intothecorrespondingANSYSformat.
A “*.cdb” file is generated when the kiln temperature field is outputted by CFD.
During the importation of the temperature field generated by CFD into ANSYS, it automatically takes the element type as solid185 which contains a surface effect.
