| Abstract: | A prediction model for extinction property of AL2O3 particle was established by using least square support vector machine. Particle swarm optimization method was applied to optimize the multi-parameters. Combined with the numerical method for radiative heat transfer, the infrared properties of emitting and scattering medium were obtained. The result shows that the method in this paper is capable to predict the extinction property accurately meanwhile the operation rate has great enhancement. |
