【Abstract】 Combined with Intra3D, the virtual demonstration of the temperature field in a fluidized bed combustor is discussed. Eulerian models to describe the gas-solid two phase flow in the fluidized bed combustor(FBC), and the combustion models of volatile release and char combustion are presented. Combined with self-defined functions, the FLEUNT CFD software is selected to simulate the process in CFB. The result data are kept as a database. Based on the simulation result of the temperature field in the fiuidized bed combustor and computer graphic technology,the iso-temperature profile is set up in CFB through Marching Cube method and particle system-based fire model. The virtual combustion fire is built. The virtual demonstration technique can be used to study and simulate the properties of thermal systems instead of experimental methods.更多还原
