光反射⁃透射测量方法在颗粒分形聚集体几何形貌重建中的应用
Application of Light Reflectance-Transmittance Measurement Method to Reconstruct Geometrical Morphology of Particle Fractal Aggregates
摘要
Abstract
Particles,including soot,aerosol and ash,usually exist as fractal aggregates. The radiative properties of the particle fractal aggregates have a great influence on studying the light or heat radiative transfer in the particle medium. In the present work,the performance of the single-layer inversion model and the double-layer inversion model in reconstructing the geometric structure of particle fractal aggregates is studied based on the light reflectance-transmittance measurement method. An improved artificial fish-swarm algorithm(IAFSA)is proposed to solve the inverse problem. The result reveals that the accuracy of double-layer inversion model is more satisfactory as it can provide more uncorrelated information than the single-layer inversion model. Moreover,the developed IAFSA show higher accuracy and better robustness than the original artificial fish swarm algorithm (AFSA) for avoiding local optimization problems effectively. As a whole,the present work supplies a useful kind of measurement technology for predicting geometrical morphology of particle fractal aggregates.关键词
