Stirling 发动机燃烧及换热分析

基于碳氢燃料燃烧化学平衡反应计算，得到燃烧产物温度及组分成份，在此基础上计算燃气物性，从而计算了热气机外燃系统加热管的对流换热系数、辐射换热系数及后排换热管的肋片换热，对燃用空气和液氧两种燃烧情形进行了对比计算，并计算了各种因素对燃烧的影响，对计算结果进行了分析和讨论，得到了很有价值的结论，为热气机外燃系统结构设计提供了借鉴。

Analysis of a Stirling Engine Combustion and Heat Exchange

On the basis of a calculation of hydrocarbon fuel combustion chemical equilibrium reaction obtained are the temperature and component ingredients of the combustion products.Following this the combustion gas physical properties were calculated and based on this the convection heat exchange factor, radiation heat exchange factor and rear row hear exchange pipe rib heat transfer of a heat engine outer combustion systen heating pipe were also calculated.A contrast computation is conducted of the two combustion conditions, air combustion and liquid oxygen combustion .Also computed are the various factors which have an influence on combustion with an analysis and discussion performed for the calculation results.The valuable conclusions obtained can serve as a guide for the structural design of the heat engine outer combustion system.
