基于现象的复杂系统建模方法

Phenomena-Based Modeling Methodology Research of Complex System

提出了基于现象的复杂系统建模方法,给出了不同尺度间的耦合方案。将单体管式固体氧化物燃料电池(SOFC)划分成流动现象、传热现象以及反应扩散现象。对流动、传热现象采用CFD模型,对反应扩散现象采用格子波尔兹曼(LBM)模型。并且采用全局型的数据库对流动、传热以及反应扩散现象进行耦合。

A phenomena-based modeling methodology was proposed and the coupling scheme of different scales was given. Monomer to the solid oxide fuel cell （SOFC）was divided into flow, heat transter and reaction-diffusion phenomena. The folw and heat transter phenomena were simulated with CFD methodology and the reaction-diffusion phenomena was simulated with Lattice Boltzmann methodology. The flow, heat transfer and reaction-diffusion phenomena were coupled by a database.
