摘要
传热特性是蜂窝夹层板的一个主要性能指标。该研究结合空间应用的特殊性,介绍了蜂窝夹层板传热性能的研究方法,主要包括Swann-Pittman类方法、有限体积法、宏观热阻法、热叠层理论等效方法、有限元方法、净热流法和试验分析。讨论了它们各自存在的问题。并提出了需要进一步完善的方法:瞬态特性求解方法及不同方向/多变量的试验研究。
Heat transfer of honeycomb sandwich panels used in aerospace industry is a main characteristic.Its research history and recent development are introduced systemically.The methods of heat transfer research include the Swann-Pittman semi-empirical relationship and its improved approach,FVM,thermal resistance analysis,improved thermal lamination theory,FEM,heat flow analysis and thermal experiment.The problems related to their precision in calculation and applications are also discussed.Finally,it is recommended that the progress trends of heat transfer of honeycomb sandwich panels will be focused on calculating the transient thermal performance,the 3-D anisotropy and several variables thermal experiment.
