将构形理论引入多孔介质气-固反应问题中进行研究,首先以三角形单元体为研究对象,以传热传质过程中的熵产生最小为优化目标,对给定微小区域进行外形优化;在此基础上,将得到的最优结构的三角形单元体组装成新的矩形构形体,进行同样的构形优化;持续类似工作直至覆盖整个控制体,得到了完整的解析解;由数值计算分析了相关参数对熵产生的影响;与相关文献中以矩形单元体为基础进行构形优化得到的结果进行了比较分析.
In order to solve the problem of gas-solid reaction in porous media, the thesis first takes the triangular element body as the research object, and optimizes the entropy generation in the heat and mass transfer process to optimize the shape of the given micro-area. On this basis, the triangular structure of the optimal structure is assembled into a new rectangular structure, and the same configuration optimization is carried out. A similar work is continued until the entire control structure is covered, and a complete analytical solution is obtained. By numerical calculation and analysis The influence of related parameters on the entropy generation; and the comparative analysis of the results obtained from the configuration optimization based on the rectangular unit body in the related literatures.
