Abstract The decentralized fuzzy inference method (DFIM) is applied to solve the inverse geometry design of a 2D radiative enclosure filled with gray participating medium. The heat transfer process in the irregular enclosure is solved using the discrete ordinate method in body-fitted coordinate. The simulated surface heat flux is employed as measurement signals. The design task is formulated as an inverse problem which is solved by the DFIM. Retrieval results illustrate that the design purpose of producing a uniform distribution of radiative heat flux on the design surface can be successfully satisfied using the present method. The DFIM is proved to be more efficient than other inverse techniques. Moreover, the effects of the number of measurement points and radiative properties of participating medium on the inverse design results are investigated. The DFIM is effective in designing the geometry of radiative enclosures for different kinds of participating media.

分散模糊推理方法在辐射围护结构逆几何设计中的应用

摘要 应用分散模糊推理方法(DFIM)求解填充灰色参与介质的二维辐射箱体的逆几何设计。使用贴体坐标中的离散纵坐标法求解不规则围护结构中的传热过程。模拟的表面热通量被用作测量信号。设计任务被表述为由 DFIM 解决的逆问题。检索结果表明，使用本方法可以成功满足在设计表面产生均匀分布的辐射热通量的设计目的。DFIM 被证明比其他逆技术更有效。而且，研究了测量点的数量和参与介质的辐射特性对逆向设计结果的影响。DFIM 在为不同类型的参与介质设计辐射外壳的几何形状方面是有效的。
