| 中文摘要 | 为强化微重力条件下相变材料的熔化释冷过程,采用仿生优化的思想和有限元方法研究了导热空间内高导热材料的最佳布置方案。研究表明,采用温度梯度的时间积分作为布置高导热材料的判断标准,可把导热仿生优化的思想的应用由稳态问题扩展到非稳态具有相变的问题。和人工构造方案法相比,仿生优化得到的方案可以明显强化释冷过程、降低热流入口温升;且能克服其工作量大,所得方案不一定包含最优方案的不完备性问题。; To enhance the cold release from phase change material (PCM) under the condition of microgravity,the iea of bionic optimization and the Finite Element Method have been taken to study the optimum arrangement scheme of high conuctivity material (HCM).Results show that with time intergration of thermal graient as criterion to determine where to locate HCM the application of the idea of bionic optimization can be extended from the steady heat conuction problem to the unsteay one with phase change.Compared with the method of man-made arrangement schemes,the arrangement of HCM gained by the method of bionic optimization can obviously enhancethe cold release and lower the temperature rise at the entrance of heat flux,an the bionic metho can also overcome its isavantage of large work and the un-complete problem that the schemes obtained by the metho of man-made arrangment scheme may not include the optimum one.; 国家"863"高技术项目(项目号863 2 2 3 3) |
