化学激光器燃烧室传热过程分析

Analysis of the heat transfer in a chemical laser combustor

为了对化学激光器燃烧室传热特性问题进行研究,通过理论分析和实验对比,建立了化学激光器燃烧室传热模型。激光器长时间运行,燃烧室传热达到稳定时,通过迭代方法可以对燃烧室稳态传热过程及相关参数进行计算。激光器短时间运行时,燃烧室壁面传热来不及达到稳定状态,其传热过程为非稳态传热过程。化学激光器燃烧室传热模型的建立,对提升激光器燃烧室传热理论、优化燃烧室反应等具有一定的参考价值。

In order to research the characteristics of heat transfer in a chemical laser combustort,he heat transfer model was founded through theoretic analysis and experiment contrast.When the runtime of chemical laser is longt,he heat transfer of combustor reaches stabilization.It can calculate the stable heat transfer process and correlative parameters by the iterative method.While the runtime of chemical laser is littlet,he heat transfer of combustor can not reach stabilizationa,nd the heat transfer process is unstable.The heat transfer model might be referrible to improve the heat transfer theory and to optimize the combustion reaction in a chemical laser combustor.
